Abstract: This invention comprises certain analogs of the prostaglandins in which the double bond between C-13 and C-14 is replaced by a triple bond. Also provided in this invention, are novel chemical processes and novel chemical intermediates useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.
Abstract: Cycloalkanones (C.sub.5-12) are converted to the corresponding 1,2-cycloalkanediones by autoxidation in the presence of a base catalyst (potassium t-butoxide preferred) and a polar organic solvent.
Abstract: 6-(o-halophenyl)-1-methyl-4H-s-triazolo[4,3-a][1,4]-benzodiazepines of the following formula: ##STR1## wherein the substituent "Hal" is either of the halogens having an atomic number up to 35, inclusive, i.e., fluoro, chloro or bromo, and their pharmacologically acceptable acid addition salts which are especially useful as muscle relaxing and anxiolylic agents.
Abstract: Certain benzoyl chloride phenylhydrazones have been found to be active against insects and mites. The benzoyl ring and the phenylhydrazone ring can be substituted with a halogen atom, a nitro group, or an alkyl group of from 1 to 6 carbon atoms, inclusive. A new class of pentahalobenzoyl chloride phenylhydrazones is described, particularly pentafluorobenzoyl chloride phenylhydrazones. A further new class of alkylbenzoyl chloride phenylhydrazones, particularly p-toluoyl chloride phenylhydrazones are also described. The compounds are prepared by reacting a benzoic acid phenylhydrazide with phosphorus pentachloride to obtain a benzoyl chloride (dichlorophosphinyl)phenylhydrazone that is reacted with phenol to produce the desired benzoyl chloride phenylhydrazones. Certain of the compounds can be prepared by direct chlorination of a benzaldehyde phenylhydrazone. Methods of use and compositions are described.
Abstract: Novel hydrogenated pyrimidine nucleosides and nucleotides are produced by catalytic hydrogenation, particularly in the presence of a rhodium catalyst. The novel compounds are specifically used to inhibit deaminating enzymes, which would inactivate cytosine arabinoside by conversion to uridine arabinoside. Cytosine arabinoside is used for its anti-viral, particularly anti-herpes and anticytotoxic activity in mammals and birds, as well as to destroy phages which interfere with the production of antibiotics. Novel formulations containing cytosine arabinoside and the hydrogenated pyrimidine nucleosides are advantageous to provide prolonged cytosine arabinoside effects.
Abstract: It has now been discovered that novel compounds of the figure below and their pharmaceutical compositions are useful in the prophylactic treatment of sensitized humans and animals for allergy and anaphylactic reactions of a reagin or non-reagin mediated nature.
Abstract: Substituted phenyl and naphthyl esters of PGE.sub.2 analogs, including the 16-alkyl, 16-fluoro, 16-phenoxy, and phenyl-substituted analogs, and their 15-epimers, and their racemic forms, and processes for producing them are disclosed. The products are useful for the same pharmacological and medical purposes as these PGE.sub.2 analogs, and are also useful as a means for obtaining highly purified 16,16-dimethyl-PGE.sub.2, 16-phenoxy-17,18,19,20-tetranor-PGE.sub.2, and 17-phenyl-18,19,20-trinor-PGE.sub.2.
Abstract: Polyamide-imides are described which are derived by conventional procedures from 2,2-bis[4-(p-aminophenoxy)-phenyl]propane (or the corresponding diisocyanate) and trimellitic acid (preferably through the anhydride acid chloride). Copolyamide-imides derived from trimellitic acid, the above diamine (or diisocyanate) and certain other aromatic diamines or diisocyanates (4,4'-diaminodiphenyl ether, m-phenylene diamine and corresponding diisocyanates are preferred) are also described. The above polyamide-imides are engineering thermoplastics which, unlike closely related polyamides and polyimides, can be extruded and injection molded to form parts having good mechanical properties.

Abstract: An improved molding apparatus is described for use with relatively light weight molds, particularly molds for articles having a plurality of voids therein. A light weight two-piece mold, one-half being substantially rigid and the other relatively flexible, is disposed in a jig. The two halves of the mold are held in sealing relationship by inserting a hollow inflatable bag between the exterior of the relatively flexible mold piece and the interior wall of the adjacent jig member and inflating said bag to a pressure superior to that exerted by the expanding foam mix in the mold.The use of the improved apparatus obviates the need for molds of high structural strength (and hence excessive weight) and gives molded articles, particularly those of complex configuration, which are free from flashing.
Abstract: Animals, especially birds and murine pests, are repelled by .gamma.- or .omega.-amino-.alpha.,.alpha.-diphenylalkanoamides, their acid addition and quaternary ammonium salts, their N-oxides, and acid addition salts of the N-oxides. The active agents can be coated on grains in order to repel animals especially birds. Animal pest damage to mature crops for harvest and newly planted seeds is prevented.

Abstract: A process is described for the isolation, in a solid state, of polyimides particularly those prepared by interaction of a polyisocyanate and a polycarboxylic anhydride in an organic solvent. A solution of the polyimide is passed into water preferably in the form of droplets or as extruded thin strands. The droplets or strands can be chopped, ground or otherwise comminuted after solidification. The process is particularly applicable to the isolation of solvent-soluble polyimides prepared by reaction of benzophenone tetracarboxylic dianhydride with a mixture of methylenebis(phenyl isocyanate) and toluene diisocyanate.
