Design, Synthesis, and Biological Evaluation of Potent Thiazine- and Thiazepine-Based Matrix Metalloproteinase Inhibitors
摘要:
The synthesis and enzyme inhibition data for a series of thiazine- and thiazepine-based matrix metalloproteinase (MMP) inhibitors are described. The thiazine- and thiazepine-based inhibitors were discovered by optimization of hetererocyclic sulfonamide-based inhibitors. The most potent series of inhibitors was obtained by modification of the amino acid D-penicillamine. This amino acid provides a gem-dimethyl group on the thiazine or thiazepine ring which has a dramatic effect on the in vitro potency of this series. In particular, the sulfide 4a and the sulfone 5a were potent, broad-spectrum inhibitors of the MMPs with IC50's against MMP-1 of 0.8 and 1.9 nM, respectively. The binding mode of this novel thiazepine-based series of MMP inhibitors was established based on X-ray crystallography of the complex of stromelysin and 4a.

Cyclicenamines are important synthons for many synthetic and pharmacological targets. Here, we report an inexpensive, catalyst-free, multigram-scale synthesis for cyclicenamines with exocyclic double bonds and four- to seven-membered rings. This strategy is more conducive to scale up, permissive of functionalization around the cyclic system, and less sensitive to the nature of the N-protecting group

2‐Cyclaminmethanole 3 werden in 2‐Cyclaminmethanthiole 7 umgewandelt, aus denen durch oxidative Chlorierung cyclisch substituierte Taurinsäure‐chloride 8 zugänglich sind. Durch Behandlung mit Basen werden 8 in die bicyclischen β‐Sultame 9 überführt. Spektroskopische Eigenschaftenund Solvolyseverhalten von 9 werden diskutiert.
