Abstract: Novel hydrogel compositions of diester crosslinked polyglucans and a process for their preparation are provided. Amylose, dextran, and pullulan succinates and glutarates when crosslinked as described were found to not only have use as general fluid sorbants but also to have exceptional hemostatic activity, adherence to a wound, and bioabsorption without causing undue irritation of the tissue or toxic effects. Reticulated hydrogel sponges made of the crosslinked diesters which are particularly useful as general fluid sorbants, and those of amylose succinate and amylose glutarate are most excellent bioabsorbable hemostatic agents. The sponges are made by lyophilizing water-soluble salts of the mono- or half-esters, such as water-soluble salts of amylose succinate or amylose glutarate, under process conditions of the invention in the presence of a reticulating agent which causes a controlled melting of the salt solution as it nears the dry state during the lyophilizing step.

Abstract: There is disclosed a new Ubiquitous Immunopoietic Polypeptide (UBIP) which has been isolated in fluffy white powder form from bovine thymus but which has been found to be present in living cellular tissue of all animals and plants tested including various guinea pig tissues, cells in tissue cultures and tissues from birds, fish, squid, plants, fungi and bacteria, the polypeptide being characterized by its ability to induce in vitro, in nanogram concentrations, the differentiation of both T cell and B cell immunocytes from precursors present in bone marrow or spleen and thus the polypeptide is useful in therapeutic areas involving thymic or immunity deficiencies and the like. The polypeptide also exhibits hypotensive properties. The polypeptide is isolated from living source materials by a combination of sizing techniques and ion-exchange chromatography and may be described by the following amino acid structural sequence:H.sub.

Abstract: There is disclosed a tridecapeptide of the following sequence:H.sub.2 N--Gly--Glu--Gln--Arg--Lys--Asp--Val--Tyr--Val--Gln--Leu--Tyr--Leu--COOHthis tridecapeptide has the capability of including the differentiation of T lymphocytes but not of complement receptor (CR.sup.+) B lymphocytes and thus is useful in a number of therapeutic areas. Also provided are novel intermediate polypeptides and methods of manufacture of the peptides.

Abstract: Primary aliphatic (preferably alkyl) mercaptans are prepared by heating a phosphorus-sulfur compound, preferably a primary aliphatic phosphorodithioic acid, with a basic nitrogen compound. The preferred basic nitrogen compounds are amines and particularly aliphatic primary and secondary amines, especially alkylene polyamines.

Abstract: 1-(2-Naphthylmethyl)-3,4,5,6-tetrahydro-2(1H)pyrimidone possesses pharmacological activity as an antianxiety agent and as an antidepressant agent.

Abstract: Two sucrose hepta-acetates, useful as synthetic intermediates in the preparation of functional sucrose derivatives, are obtained by tritylating sucrose, acetylating the resulting mixture of monotritylsucroses, and detritylating the resulting mixture of monotritylsucrose hepta-acetates. The previously known compound, 1',2,3,3',4,4',6-hepta-O-acetylsucrose, can be recovered by crystallization from the solution obtained in the detritylation step. When the remaining solution is subjected to retritylation and chromatography, it yields a new compound, 1',2,3,3',4',6,6'-hepta-O-acetylsucrose.

Abstract: 1-N-Alkyl-4,6-di-(aminoglycosyl)-1,3-diaminocyclitols, valuable as antibacterial agents, are prepared by treating an acid addition salt of a 4,6-di-(aminoglycosyl)-1,3-diamonocyclitol antibacterial agent in an inert solvent, preferably a protic solvent containing water, with one equivalent of a hydride donor reducing agent and with at least one equivalent of an aldehyde.The 1-N-alkyl-4,6-di-(aminoglycosyl)-1,3-diaminocyclitols are also prepared by treating the corresponding 1-N-acyl-4,6-di-(aminoglycosyl)-1,3-diaminocyclitol with an amide-reducing hydride reagent in an inert organic solvent.Other methods of preparing 1-N-alkyl-4,6-di-(aminoglycosyl)-1,3-diaminocyclitols include carrying out the foregoing processes with partially N-protected intermediates. Another useful process involves preparing a Schiff base of the 1-amino function of a partially N-protected 4,6-di-(aminoglycosyl)-1,3-diaminocyclitol followed by reduction of said Schiff base and removal of the N-protecting groups.
