Abstract: Novel interphenylene derivatives of 11,12-secoprostaglandins are prepared by the stepwise alkylation of the ethyl ester or the t-butyl ester of acetoacetic acid. One such method involves treatment of the t-butyl ester of acetoacetic acid with a strong base to form the anion followed by treatment with ethyl p-(3-bromopropyl)benzoate to produce ethyl 4-(4-tert-butoxycarbonyl-5-oxo-hexyl)benzoate, subsequently reacting the anion of the thus-formed benzoate with 1-chloro-4-acetoxynonane to produce ethyl 4-(4-acetyl-4-tert-butoxycarbonyl-8-acetoxytridecyl)benzoate followed by decarboxylation and alkaline hydrolysis to produce the desired product 4-(4-acetyl-8-hydroxytridecyl)benzoic acid which is useful as a pharmaceutical in the treatment of patients with renal failure and in the prevention of transplant rejection.

Abstract: Interphenylene 8-aza-9-dioxothia-11,12-secoprostaglandins are prepared by the two-stage alkylation of the anion of a lower alkyl sulfonamide, R.sup.1 SO.sub.2 NH.sub.2, using first a compound of the formula: ##STR1## and second, a compound of the formula: ##STR2## The compounds produced have renal vasodilatory activity when administered orally and are therefore useful for treating patients with renal impairment.

Abstract: Ethylcellulose walled microcapsules, obtained from cyclohexane medium are heavily solvated with cyclohexane and tend to form lumps even after drying. Displacements of cyclohexane by pentane, hexane, heptane or octane or mixtures thereof during the isolation of the microcapsules gives a dry product which is essentially all discrete dry microcapsules.

Abstract: Acids, particularly dilute acid solutions thickened with copolymers of dimethyl diallyl ammonium chloride and a monomer capable of postreaction after polymerization to provide branching or partial crosslinking, are useful as oil well drilling and fracturing fluids for stimulating well production.

Abstract: Novel polymers having a linear backbone which is free from both branching and cross-linking, comprising quaternized nitrogen atoms linked to each other through trimethylene groups. By the term "linear backbone" is meant that the polymer has only acyclic groups, i. e. trimethylene, linking the nitrogen atoms in a single continuous chain; the polymer is free from "branching" when it has no repeating monomer units extending from the polymer backbone; and it is free from "cross-linking" when there is no joining of two linear backbones. These polymers are useful as antimicrobials, flocculating agents, antistatic agents, electroconductive agents for coating paper, chelating agents and bile acid binding agents, as well as in similar applications where their high charge to weight ratio and fully accessible nitrogen atoms can be employed. The polymers are obtained by the polymerization of dihydro-oxazine, reductive alkylation of the resulting polymer, followed by quaternization.

Abstract: This invention relates to 11,12-secoprostaglandins and processes for their manufacture. These compounds have prostaglandin-like biological activity and are particularly useful as renal vasodilators, for the treatment of hypertension, for the prevention of thrombus formation, in preventing gastric secretion, and as regulators of the immune response.

Abstract: The invention disclosed herein relates to a novel process for preparing the monomer, 3-[N-(3-chloropropyl)methylamino]-N,N,N-trimethyl-propan-1-aminium chlorid e, which comprises reacting N,N-bis(3-chloropropyl)methylamine with trimethylamine. The 3,3-ionene monomer thus obtained is a key intermediate for making the linear, unbranched, non-cross-linked polymer, poly-[{methyl-(3-trimethylammoniopropyl)imino}trimethylene dichloride], which is valuable as an oral bile acid sequestrant.
