(Res. Lab., Merck Sharp and Dohme, West Point, Pa., USA). J. Med. Chem., 20(1), 35-43 (English) 1977. CODEN: JMCMAR. DOCUMENT TYPE: Journal CA Section: 2 (Hormone Pharmacology) Section cross-reference(s): 23 Of 23 satd. and unsatd. acylhydroxyalkanoic acids, prepd. by alkylation of tert-Bu acetoacetate [1694-31-1] with Et 7-bromoheptanoate [29823-18-5] followed by alkylation with an acetoxy-substituted alkyl halide, decarboxylation, and sapon., a no. had prostaglandin-like activity in vitro, affinity for the prostaglandin receptor, and some characteristic activity in vivo. 8-Acetyl-12-hydroxyheptadecanoic acid (I) [54314-53-3] markedly raised cyclic AMP [60-92-4] levels in the mouse ovary at concns. in the pharmacol. 54315-38-7 and 54315-35-4 which are cas registry numbers of substances are two of reagents here. range, and showed significant affinity for prostaglandin receptor. I administered i.v. had renal vasodilatory activity in dogs, compared to the necessity of renal artery infusion of PGE1 [745-65-3] due to metabolic inactivation. Orally administered I inhibited collagen-induced platelet aggregation in guinea pigs, while PGE1 is not orally active. Structure-activity relations are discussed. .
Blocked diisocyanates from diisocyanatomethylnorbornane and acetoacetic acid alkyl esters, useful as crosslinking agents
Blocked diisocyanates from diisocyanatomethylnorbornane and acetoacetic acid alkyl esters, useful as crosslinking agents. Dalibor, Horst (Hoechst A.In this experiment, several chemicals are used like 64340-57-4 -G., Ger.). Ger. DE 2612786 23 Jun 1977, 10 pp. (German). (Germany). CODEN: GWXXAW. CLASS: IC: C07C103-44. APPLICATION: DE 76-2612786 25 Mar 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Partially and fully blocked diisocyanates were prepd. by the reaction of 1,3-diisocyanato-7-methylnorbornane (I) [64340-65-4] with MeCOCH2CO2R (R = C1-5 alkyl) and were used as crosslinking agents for coating compns. contg. epoxy resins, melamine resins, hydroxyalkyl methacrylate copolymers, etc. The blocked diisocyanates were liqs. at 10-80.degree.. Thus, 162 g MeCOCH2CO2CMe3 [1694-31-1] contg. 0.15 g Zn acetylacetonate was treated slowly at 95.degree. with 99 g I to prep. a blocked diisocyanate (II) [64340-54-1] with NCO content 0.92% and Gardner-Holdt viscosity Z6. An epoxy resin contg. II gave a coating having good luster, high flexibility, no yellowing, and improved solvent and weather resistance. .
