  • Patent number: 9861653
    Abstract: The present invention provides an anti-cancer lipid-based composition that kills very aggressive pancreatic cancer cells and breast cancer stem cell (CSC)-like cells. This composition is a concoction of an anti-cancer agent, ESC8 and a glucocorticoid receptor (GR)-targeting cationic lipid delivery system, DX which is further complexed with plasmid DNA. This composition shows anti-cancer effect and initiates killing of cancer cells and CSC-like cells within 3 h. When anti-cancer gene encoded plasmid is used, residual cancer cells were also significantly eradicated after 2 days of exposure. The formulation-free naked ESC8 requires at least ten-fold more concentration and 3 days of continuous treatment to get a similar level of killing. The composition could also inhibit the tumor growth in mice orthotopically implanted with very aggressive mouse breast cancer cell, ANV-1. This cell is known to produce breast CSC-like cells that show phenotype of advanced cancer relapsing.

  • Patent number: 9763881
    Abstract: The present invention relates to a formulation in which glycolipids and phospholipids, isolated from rice bran gum samples, were used in conjunction with gene carrying lipids to test its efficacy in delivering genes to cancer cells selectively. This formulation did not mediate efficient delivery of genes to non-cancerous cells, thus, showing potential use of this formulation to deliver anticancer therapeutics to cancer cells without eliciting treatment related toxicity to normal cells.

  • Patent number: 9364566
    Abstract: The present invention relates to a cationic lipid based aqueous formulation comprising cationic lipid, dexamethasone and a neutral co-lipid, wherein the said formulation is useful for selective targeting and delivering gene to glucocorticoid receptor expressing cancer cells. Glucorticoid receptors (GR) express in various normal and cancer cells. A lot of ligand activated physiological functions are known involving GR but its role in cancer progression (if any) is not clearly understood. Synthetic GR antagonist, dexamethasone (Dex) finds use as anti-inflammatory drug and is known to induce apoptosis in cancer cells. This Dex is included in a cationic lipid-based formulation as a co-lipid to deliver to and express genes specifically in cancer cells possibly through expressed GR. Gene delivery to cancer cells is independent of the gene construct, and tumor cell line. Normal transformed cells expressing GR but with no cancer lineage show much smaller level of transfection.

  • Patent number: 8012952
    Abstract: The present invention provides a novel series of cationic, lipid-based, 17?-substituted-estradiol derivatives. The present invention further provides a process for the preparation of a novel series of 17?-substituted-estradiol derivatives. The invention also provides information about highly selective anticancer activities of these molecules in estrogen responsive cell lines. The compound elicits high level of toxicity to gynecological cancer cell lines such as MCF-7, T47D (estrogen receptor positive cell lines), MDA-MB-468 (estrogen receptor knock-out cell line), HeIa (cervical cancer). The present class of cationic lipid-based, estradiol derivatives is likely to find specific use in developing target specifically deliverable anticancer drugs for the treatment of gynecological cancers that are most prevalent in women population irrespective of ethnicity.
