Development of Dual-Acting Agents for Thromboxane Receptor Antagonism and Thromboxane Synthase Inhibition. 3. Synthesis and Biological Activities of Oxazolecarboxamide-Substituted ω-Phenyl-ω-(3-pyridyl)alkenoic Acid Derivatives and Related Compounds
摘要:
A novel series of oxazolecarboxamide-substituted omega-phenyl-omega-(3-pyridyl)alkenoic acid derivatives was discovered as potent dual-acting agents to block the TXA(2) receptor and to inhibit the thromboxane synthase (TRA/TSI). Synthesis, structure-activity relationship (SAR), and in vitro and in vivo pharmacology of this series of compounds are described. Modification of the series revolved around the oxazole moiety to increase the hydrophilicity of the compounds and to correlate the biological activity with lipophilicity of the compounds. The most potent in the series was (E)-7-[4-[4-[[(4-cyclohexylbutyl)amino]carbonyl]-2-oxazolyl]phenyl]-7-(3-pyridyl)hept-6-enoic acid (14) with K-d = 9.9 +/- 0.4 nM for the thromboxane receptor antagonism and IC50 = 55.0 +/- 17.9 nM for thromboxane synthase inhibition. The compound 14 was a selective TRA/TSI which exhibited desirable characteristics for oral activity, "shunt" effect to elevate PGI(2) level, and absence of agonist activity.

Compounds of formula (I): wherein R1 is C1-6alkylamino, or C1-6alkoxy; m is an integer having a value of 2 or 3; n is an integer having a value of 0 to 3; p is an integer having a value of 1 or 2; and salts thereof are inducers of human interferon. Compounds which induce human interferon may be useful in the treatment of various disorders, for example the treatment of allergic diseases and other inflammatory conditions for example allergic rhinitis and asthma, the treatment of infectious diseases and cancer, and may also be useful as vaccine adjuvants.
A simple and general red light-induced oxidation of organoboron compounds to obtain hydroxyl has been developed with spinach as the photocatalyst in alcohol. This mild protocol shows broad substrate scope and provides a wide range of aliphatic alcohols and phenols in moderate to excellent yields. Notably, the robustness of this method is suitable for B(OH)2, Bpin, Bneo and BF3K substrates that respond
已经开发了一种简单且通用的红光诱导有机硼化合物氧化以获得羟基,菠菜作为醇中的光催化剂。这种温和的协议显示了广泛的底物范围,并以中等至优异的产量提供了广泛的脂肪醇和酚。值得注意的是,该方法的稳健性适用于 B(OH) 2、Bpin、Bneo 和 BF 3对不同光(包括红色、蓝色和阳光)作出反应的 K 底物。更大规模的实验和绿色化学指标分析证明,这是一种稳健且绿色的方法,甚至可以仅使用厨房设备和配料进行。进一步的机理研究表明,该反应可能涉及由光诱导电子转移过程产生的超氧阴离子自由基。
