  Potential antisecretory antidiarrheals. 2. .alpha.2-Adrenergic 2-[(aryloxy)alkyl]imidazolines

  摘要：

  Lofexidine, an alpha 2-agonist, has central hypotensive activity and peripheral intestinal antisecretory activity. Analogues were synthesized with increased polarity in an attempt to prevent penetration of the blood-brain barrier. The compounds were evaluated in the cholera toxin treated ligated jejunum of the rat and in the Ussing chamber with a rabbit ileum preparation. Active compounds were determined to be alpha 2-adrenergic agonists by yohimbine reversals of their Ussing chamber activities. The 2,6-dimethyl derivative of lofexidine, 4a, was as active as lofexidine in vivo, but derivatives with 2,6-substituents larger than ethyl were inactive. (Aryloxy)alkyl derivatives which have an imidazoline and a methyl or larger group as part of the alkyl exhibited the best antisecretory activity. Compounds with substituents in the para position of the phenyl ring were generally inactive. 3-Amino-2,6-dimethyl derivative 21 was twice as active as 4a. A 2-methyl substituent is required in the 3-amino series to retain good activity. 2-Methyl derivative 12a had activity comparable to that of 4a, while 6-methyl derivative 12f was inactive. Substituents on the 3-amino group did not affect the activity, but substituting a hydroxyl for the amino group produced an inactive compound. Replacing the phenyl moiety with a 4-indole resulted in retention of activity, but other heterocycles were inactive. Compound 12a was resolved and d isomer 32 was five times more potent than l isomer 33. The more active compounds in the rat cholera toxin assay (RCTA), when evaluated in the dog, exhibited antisecretory activity but also exhibited central nervous system (CNS) effects, sedation and ataxia, at 10 mg/kg, and in spontaneously hypertensive rats at 50 mg/kg. A measure of polarity, log P, was calculated for the (aryloxy)alkyl groups. Regression analysis showed no correlation of antisecretory ED50 to the calculated log P. The active compounds did not show a separation of the central CNS effects from the peripheral antisecretory activity by increasing the polarity.

Other tetramethyl-3-pyrrolinecarboxamide compounds were synthesized by acylating the aminoalkyl compounds with 2,2,6,6-tetramethyl-3,5-dibromo-4-piperidinone in a reaction involving Favorskii rearrangement. Saturation of the double bond of some pyrroline derivatives furnished the pyrrolidinecarboxamides. The new compounds of each

  between PDE3A and B represents a massive obstacle for obtaining selectivity at the active site; however, utilization of libraries with high molecular diversity in high throughput screens may uncover selective chemical matter. Herein, we employed a DNA-encoded library screen to identify PDE3B-selective inhibitors and identified potent and selective boronic acid compounds bound at the active site.

  人类遗传证据表明 PDE3B 与代谢和血脂异常表型相关。多种PDE3家族选择性抑制剂已获得FDA批准用于多种适应症；然而，考虑到心脏中不良的致心律失常作用，对密切相关的家族成员（例如 PDE3A；48% 同一性）的 PDE3B 抑制的选择性是开发 PDE3B 疗法的关键考虑因素。 PDE3B 相对于 PDE3A 的选择性可以通过多种方式实现，包括化合物固有的特性或组织选择性靶向。 PDE3A 和 B 之间的高活性位点同源性 (>95%) 是在活性位点获得选择性的巨大障碍；然而，在高通量筛选中利用具有高分子多样性的文库可能会发现选择性化学物质。在此，我们采用 DNA 编码库筛选来鉴定 PDE3B 选择性抑制剂，并鉴定出结合在活性位点的有效且选择性的硼酸化合物。

  Starting from palinavir (1), our lead HIV protease inhibitor, we have discovered a new series of truncated analogues in which the P-3-P-2 quinaldic-valine portion of 1 was replaced by 2',6'-dimethylphenoxyacetyl. With EC50's in the 1-2 nM range, some of these compounds are among the most potent inhibitors of HIV replication in vitro, reported to date. One of the most promising members in this series (compound 27, BILA 2185 BS) exhibited a favorable overall pharmacokinetic profile, with 61% apparent oral bioavailability in rat. X-ray crystal structures and molecular modeling were used to rationalize the high potency resulting from incorporation of this structurally simple, achiral ligand into the P-3-P-2 position of hydroxyethylamine-based HIV protease inhibitors.
