BACKGROUND AND PRIOR ART REFERENCES

Indian green mussels (Perna viridis) are the cheap source of proteins and considered as a delicacy. Extract prepared from green mussels by enzyme-acid hydrolysis process showed various biological activities. In our earlier patent (US patent application #20030044470) we have shown the inhibition of osteoclast differentiation and activation in the crude extract. In same continuation, attempts have been made to purify the active compound that showed inhibition of osteoclast differentiation and activation. The purification of the crude extract was done using HPLC, gel filtration and TLC methods. The purified compound was again checked for the above activity. The compound was characterized using NMR and LC-MS/MS techniques. This compound was synthesized and checked for the presence of the above biological activity. This patent in particular describes the synthesis of the compound and also its activity for inhibition of osteoclast formation.

Novel class of amino acid/dicarboxylic acid derivatives (sulfonic acid/sulfate derivatives of naturally occurring amino acids and their amides) along with calcium is for their activation to show inhibition of the dendritic cells. Amino acid derivatives and calcium ion when used separately did not show any activity on differentiation of dendritic cells. The following classes of compounds are identified

- (1) Natural acidic amino acids (Aspartic acid, Glutamic acid and their amides),
- (2) Unnatural amino acids, amides such as homoglutamic acid,
- (3) Dicarboxylic acids such as succinic acid, glutaric acid, and adipic acid
- (4) N-sulfonyl, C-sulfonyl/sulfate derivatives of the above acids
- (5) Alkali and alkaline earth metals such as Na, K, Mg, Zn and Ca as their suitable salts.

A number of molecules are known to induce the differentiation and maturation of dendritic cells from precursors. Some of the recent ones are listed below:

- 1. The most studied is differentiation of DCs with GM-CSF which is the conventional method to generate DCs from bone marrow. The DCs obtained in this manner are immature in nature.
- 2. Maturation of DCs is normally obtained by stimulating the immature DCs has been shown to □). Recently TNF-□ with Tumor Necrosis Factor-alpha (TNF-induce the differentiation of DCs from monocytes.
- 3. CD40 ligand (CD401) that is normally expressed on T cells also induces the maturation of DCs. An alternative for CD401 is the use of commercially available anti-CD40 monoclonal antibody.
- 4. Stimulation with the extracellular endotoxin, Lipopolysaccharide (LPS) from Escherichia coli is also a common method to mature DCs
- 5. Atrial natriuretic peptide (ANP) a cardiovascular hormone secreted mainly by the cardiac atria regulates the volume-pressure homeostasis. The action of ANP is mediated by its receptor, guanylyl cyclase-coupled receptor A (GC-A) and has recently been shown to induce the maturation of DCs by increasing cytokine secretion and increases in various cell surface molecule expression.
- 6. The imidazoquinoline compounds imiquimod and R-848 are low-molecular-weight anti-viral compounds that are immune response modifiers and induce the synthesis of interferon-alpha and other cytokines in a variety of cell types. These compounds have potent anti-viral and anti-tumor properties and have recently been shown to induce the activation of macrophages and splenocytes and induce the maturation of Dendritic cells.
- 7. Stimulation of Flt3 receptor tyrosine kinase through its cognate ligand expands early hematopoietic progenitor and Dendritic cells (DCs) in humans and mice.
- 8. Prostaglandin E2, found at high concentrations under the skin has been shown to facilitate initiation of skin immune responses by promoting the migration and maturation of Langerhans cells, a DC subtype found under the epidermis and in the dermis of the skin.
- 9. Fermented mistletoe extract often used for adjuvant treatment of cancer patients, significantly stimulated the maturation of pre-differentiated immature DC, as evidenced by a heightened expression of CD83. Like the positive control TNF-alpha, the mistletoe extract significantly activated CD80 and CD86 as well as HLA class I and II molecules on these cells.
- 10. Lysophosphatidylcholine (LPC) is a major lipid component of oxidized low density lipoprotein with reported pro-inflammatory activities. It is now reported that LPC acts through G protein-coupled receptors on differentiating monocytes to generate mature dendritic cells with the ability to stimulate IL-2 and IFN-gamma production by allogeneic T lymphocytes.

Among the various Antigen Presenting Cells (APCs) of the immune system, Dendritic Cells (DCs) constitute the most potent APCs and act as a bridge between the innate and the acquired arm of the immune system. This is largely attributed to the ability of DCs to take-up pico- to femtomoles of antigen and to stimulate primary naïve quiescent T cells, thereby initiating a primary immune response. DCs exist in various states of activation that translates into distinct functions. For example, DCs arising from the Bone Marrow (BM) are essentially immature DCs. These DCs exhibit low levels of T cell costimulatory molecules such as CD80, CD86, CD40 & CD54 and also low levels of surface MHC class I and class II molecules. Further, these DCs express a range of phagocytic, endocytic and scavenger receptors and owing to the above features are thus programmed for antigen capture and uptake. Upon contact , bacterial endotoxins (e.g.Flwith various inflammatory stimuli such as, TNF-LPS), CD40 ligand (CD401), CpG containing bacterial DNA, double stranded viruses and certain (but not all) antigens, DCs undergo a process of maturation, wherein they now upregulate their surface levels of costimulatory molecules and MHC-peptide complexes (now exported to the cell surface following degradation and loading onto MHC trimers) and are thus programmed for antigen presentation and T lymphocyte stimulation. The transformation from the immature to the mature stage is a tightly regulated process often requiring T cell help. During maturation these DCs also secrete a range of cytokines such as and low levels of IL-10.□, IL-12, IFN-□TNF-Owing to secretion of pro-inflammatory cytokines, DCs are thought to drive pro-inflammatory or Th1 responses and help in the clearance of the pathogen. Therefore, factors/molecules that increase the population of immature DCs in the immune system offer added advantage for the host's fight against infectious pathogens. In this context efforts have been focused on finding and generating ways to increase the DC numbers in the immune system. These have included the use of recombinant DCs or even pathogens that have been transformed to express Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF), the growth factor that is conventionally used to generate DCs in vitro.

A number of studies have identified pathogen and host products such as proteins that induce the maturation of different DC subsets. Owing to their fully mature status these DCs are more programmed for antigen presentation and T cell stimulation and have reduced capacity to capture antigens of pathogens. Immature DCs that are de novo differentiated from precursors offer better advantage than mature DCs because of their ability to scavenge pathogens followed by their uptake and processing and subsequent presentation to T lymphocytes. Our observation on the ability of ‘the molecule’ to induce differentiation of Dendritic Cells from mouse bone marrow leukocyte precursors, therefore, assumes paramount importance and is a significant step towards modulation of immune responses controlled by DCs. As the DCs differentiated by ‘the molecule’ are immature in nature and resemble very closely to the DCs differentiated by GM-CSF they will be efficient not only at antigen capture but also be effective T cell stimulators.

Among the many applications, the two most important ones would include the use of ‘the molecule’ in vaccine formulations or in protection based studies that would promote more efficient and faster presentation of the antigens to T cells thereby initiate primary protective Th1 immune responses and help in the clearance of the pathogen. Further, ‘the molecule’ offers a cheap alternative to GM-CSF for commercial purposes to generate DCs in vitro for research based studies.

Basically, immuno-supression is a common clinical feature in many infectious diseases. This immuno-supression cripples the ability of the immune systems to get rid of the infectious agents eventuating in the death of the host. It has been found that the host recovering from disease after chaemotherapy shows a significant improvement of antigen-specific immune functions. Despite the urgency of the need, and immuno-potentiator which can be of human use remains awaited. The cumulative incidence of the diseases obviates the need for a drug(s) that restores the immune response of the affected individual to a normal level.

In response to any invasion by a pathogen, the complex multicellular organisms have evolved a defense mechanism to make their internal environment more hostile to invaders. All immune systems have one feature in common: they respond to infection by switching from a resting to an active state. The innate response limits the infection and activates Antigen Presenting Cells (APCs) to trigger adaptive immunity, which increases specificity and generates memory. Consequently, the immune responses that occur during an encounter with antigens-be it infectious agents or allergens are primarily characterized by the plasticity of their nature and magnitude. This feature provides an important advantage that permits the immune system to tailor its defense strategy to particular groups of antigens. Interactions between APCs such as Dendritic cells (DCs) and macrophages and the different subsets of T cells (CD4+ and CD8+) in the T cell rich areas of the lymph nodes and spleen, amplify the consequent immune responses. Following this interaction, T helper (Th) cell precursors then differentiate into effectors. that secrete either pro-inflammatory or suppressor/regulatory cytokines such as Interferon (IFN)-□E Tumor Necrosis Factor (TNF)-□, and Interleukin (IL)-1, or IL-4, IL-10 and Transforming Growth Factor (TGF)-□, respectively.

Among the most potent of the APCs are the macrophages and different subsets of DCs, that together virtually regulate the antigen capture and presentation of the innate arm of the immune system. DCs are professional APCs that are continuously produced by the stem cells in the hematopoeitic tissues. DCs exist at various states of activation that are primarily classified as immature (iDCs) and mature (mDCs). iDCs are programmed for antigen capture, which upon contact with various stimuli, such as bacterial products, CD40 ligand, (TNF)-□, and certain antigens undergo a process of maturation wherein they now become programmed for antigen presentation and T-cell stimulation. Consequently, agents that promote the maturation of iDCs play a vital role in shaping the early immune responses elicited during an infection. Along with macrophages, that constitute the all important phagocytic component of the innate immune system DCs activate the effector cells such as the various subsets of T-cells, Natural Killer (NK) cells and NK-T cells by secreting a profile of cytokines that would eventually prime these effector cells to carryout their functions. These range from stimulating the adaptive arm of the immune system for the generation of antibody mediated responses, to stimulation of the cytotoxic activity by the CD8⁺ T-cells against the infected cells/tissues. The invention may provide a novel compound that will be useful in vaccination, cancer therapy and other immunomodulatory regiments.

BRIEF DESCRIPTION OF THE ACCOMPANYING PLATES

Plate I. Compound I Induces Differentiation of Dendritic Cells from BALB/c Mouse Bone Marrow

Enriched leukocyte precursors from 4 to 6 weeks old mice were stimulated with varying concentrations of compound as given in example-3 for 48 h. Cells were stained for the surface levels of indicated markers. Plates A-D represent surface levels of CD80, CD54, CD11c and H-2D (MHC class 1), respectively. Results obtained with Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) are also shown for comparison. Panels a to d in each Plate shows the surface levels of indicated markers on cells stimulated with 15 ng/ml of GM-CSF, 10 μg/ml, 5 μg /ml and I jig /ml of compound 1, respectively. The Green line represents staining of stimulated cells while the black line depicts staining of unstimulated cells.

Differentiation of Dendritic Cells

The fine suspension obtained above was transferred into a 50 ml sterile centrifuge tube and centrifuged for 10 minutes at 1200 rpm. After removing the supernatant, RBC lysis buffer was added, mixed thoroughly and incubated for 3-5 minutes at room temperature. The pellets were washed using HBSS wash buffer and then centrifuged again for 10 minutes at 1200 rpm. This process was repeated for one more time. The pellet was dissolved in 2 ml HBSS and passed through a pre-separation filter (Miltenyi Biotech # 130-041-407) to remove unwanted tissue etc. Microbeads (I-A, CD45R and CD90) were added to this clear solution and incubated for one hour at 4° C. with shaking to eliminate other lymphocytes and macrophages and MHC positive cells. This suspension was then finally passed through a MACS (Magnetic Activated Cell Sorting) column to get essentially and predominately leukocyte precursors. The cell pellet was suspended in complete medium (RPMI 1640, 10% Foetal Calf Serum, Sodium pyruvate (1 mM) and 2-Mercaptoethanol (50 mM). About 2.5-3×10⁶leukocyte precursors were plated in each well of a 24 well culture plate in 1 ml culture volume. Cells were stimulated with either 15 ng per ml of Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) or 50 micro gram per ml of the compound (neutralized with 1 M Tris HCl to achieve a pH of 7.0). The plate was incubated for 48 hours at 37° C. in a CO₂incubator.

Evaluation of Cell Surface Marker Expression

In order to evaluate the upregulation of various cell surface markers associated with Dendritic cells, flow cytometry on the cells stimulated with GM-CSF or the compound was carried out using fluorescent labeled antibodies to various molecules (CD11c, I-A^d, CD80, CD86, H2-D^d, CD54, CD40).

Isolation of Bone Marrow

For each set of experiment a group of 4 BALB/c mice were sacrificed by transferring the animals in a chloroform chamber. The hind limbs of the mouse were removed carefully and placed in a Petri dish with HBSS (Hanks Balanced Saline Solution) wash buffer. The tibias and femurs were cleared of all surrounding and attached tissues. This was followed by chipping the ends of bones. The bone marrow was flushed out by injecting HBSS solution into the bone with the help of a hypodermal syringe (No. 26 gauge). The bone marrow was finally made into a fine suspension by syringing in and out of the fluid several times using an 18 gauge syringe needle.

A In vitro Osteoclastogenesis Assay

For in vitro osteoclastogenesis bone marrow cells were isolated from 5- to 8-wk-old Balb/c mice. Mice were sacrificed by cervical dislocation and femora and tibiae were aseptically removed and dissected free of adherent soft tissues. The bone ends were cut, and the marrow cavity was flushed out with medium MEM from one end of the bone using a sterile 21-gauge needle. The bone marrow suspension was carefully agitated with a plastic Pasteur pipette to obtain a single-cell suspension. The cells were washed twice and resuspended (10⁶cells/ml) in aMEM containing 10% FBS. Stromal cell-free, M-CSF-dependent, osteoclast precursor cells were prepared from these cells as previously described (Wani et al. 1999). Briefly, bone marrow cells were incubated for 24 h in aMEM containing 100% o FBS in the presence of M-CSF (10 ng/ml) at a density of 3×10⁵cells/ml in a 75 cm²flask. After 24 h, nonadherent cells were harvested and layered on a Ficoll-Hypaque gradient. Cells at the gradient interface were collected, washed and resuspended (5×10⁵/ml) in AMEM containing 10% FBS. In this study, we called these stromal cell-free, M-CSF-dependent, nonadherent cells as osteoclast precursors. These osteoclast precursors were added to 96-well plates (100 μl/well) containing plastic coverslips. Each well received further 100 μl of medium containing M-CSF (30 ng/ml), RANKL (30 ng/ml) without or with various concentrations of purified compound. Cultures were fed every 2-3 days and after incubation for 6 days osteoclast formation was evaluated by tartrate-resistant acid phosphatase (TRAP) staining. The number of TRAP-positive multinucleated cells (MNCs) containing 3 or more nuclei was scored.

Characterization of Osteoclasts by TRAP Staining

Osteoclast formation was evaluated by quantification of TRAP-positive MNCs as described previously (Khapli et al. 2003). TRAP is preferentially expressed at high levels in osteoclast and is considered, especially in the mouse, to be an osteoclast marker. Cytochemical staining for TRAP is widely used for identifying the osteoclasts in vivo and in vitro. It is claimed to be specific for osteoclasts in bone. After incubation, cells on cover slips were washed in PBS, fixed in 10% formalin for 10 min and stained for acid phosphatase in the presence of 0.05 M sodium tartrate. The substrate used was napthol AS-BI phosphate. Only those cells that were strongly TRAP-positive (dark red) counted by light microscopy.

In Vitro Bone Resorption Assay

Osteoclast has the ability to excavate authentic resorption lacunae in vivo and in vitro. Bone resorption is the unique function of the osteoclast and is therefore the most useful means of distinguishing it from other cell types. M-CSF-dependent, non-adherent bone marrow cells were incubated for 10 days on bovine cortical bone slices in the presence of M-CSF, RANKL with or without various concentrations of compounds. Bone slices were examined for resorption pits by reflected light microscopy as previously described (Wani et al. 1999).
