7-Aoyl-3-cephem -4-carboxylic acids, process for their preparation and compositions containing them. Cephalosperins with the formula:
in which R represents a pharmaceutically acceptable acyl group known to be utility as a substituent on the 7-amine group in cephalosporins or on the 6-amino group in penicillins have antibacterial activity. The compounds are prepared I by displacement of an acetyl group from a 3-acetoxymethyl group of an appropriately substituted cephalosporin or 7-amino cephalosporin with 1-(2- sulfamidoethyl) 1,4-dihydro-5H-tetrazole-5-thione, and if desired introducing a required 7-acyl group.

其中 R 代表已知可用作头孢菌素中 7-氨基或青霉素中 6-氨基取代基的药学上可接受的酰基,具有抗菌活性。这些化合物的制备方法 I 是用 1-(2-磺酰胺基乙基)1,4-二氢-5H-四唑-5-硫酮取代适当取代的头孢菌素或 7-氨基头孢菌素的 3-乙酰氧甲基上的乙酰基,并根据需要引入所需的 7-酰基。
The syntheses and biological evaluation of a series of novel indeno[1,2-d]thiazole derivatives are described. Several groups reported 5-HT3 receptor agonists which were mainly evaluated for their activities on the von Bezold-Jarisch reflex (B-J reflex). We discovered that tetrahydrothiazolopyridine derivative 1b had a contractile effect on the isolated guinea pig colon with weak B-J reflex. Our efforts to find a new type of 5-HT3 receptor agonists on the isolated guinea pig colon focused on the synthesis of a fused thiazole derivative 1d modified from 1b and reverse-fused thiazole derivatives (7-10). In this series, 10f (YM-31636) showed high affinity and selectivity for the cloned human 5-HT3 receptor; furthermore, it showed potent and selective 5-HT3 receptor agonistic activity. YM-31636 was examined for its effects on defecation in animals, thus evaluating the compound as an agent against constipation. (C) 2003 Elsevier Science Ltd. All rights reserved.
