Conversions by Dimethyldioxirane of 1-Alkylbenzotriazoles into Their N-Oxides and of 2-Alkylbenzotriazoles into 2-Alkyl-trans-4,5,6,7-diepoxy-4,5,6,7-tetrahydrobenzotriazoles
摘要:
Dimethyldioxirane converted 1-alkylbenzotriazoles 4 to the corresponding 3-alkylbenzotriazole 1-oxides 5 in good yields, but transformed 2-alkylbenzotriazoles 12 into 2-alkyl-trans-4,5,6,7-diepoxy-4,5,6,7-tetrahydrobenzotriazoles 13.
Cytosolic phospholipase A(2)alpha (cPLA(2)alpha) and fatty acid amide hydrolase (FAAH) are enzymes, which have emerged as attractive targets for the development of analgetic and anti-inflammatory drugs. We recently reported that 1-[3-(4-octylphenoxy)-2-oxopropyl]indole-5-carboxylic acid (10) and related compounds are inhibitors of cPLA(2)alpha. Since cPLA(2)alpha and FAAH possess several common structural features, we now screened this substance series together with some new derivatives for FAAH inhibition. Some of the assayed compounds proved to be selective cPLA(2)alpha inhibitors, while others showed high FAAH and moderate cPLA(2)alpha inhibitory potency. Furthermore, several derivatives were favorably active against both enzymes and, therefore, could represent agents, which have improved analgetic and anti-inflammatory qualities in comparison with selective cPLA(2)alpha and FAAH inhibitors.

1-Heteroarylpropan-2-ones as inhibitors of fatty acid amide hydrolase: Studies on structure-activity relationships and metabolic stability
The serine hydrolase fatty acidamide hydrolase (FAAH) catalyzes the degradation of the endocannabinoid anandamide, which possesses analgesic and anti-inflammatory effects. A new series of 1-heteroarylpropan-2-ones was synthesized and evaluated for FAAH inhibition. Structure-activity relationship studies revealed that 1H-benzotriazol-1-yl, 1H-7-azabenzotriazol-1-yl, 1H-tetrazol-1-yl and 2H-tetrazol-2-yl
丝氨酸水解酶脂肪酸酰胺水解酶(FAAH)催化内源性大麻素anandamide的降解,具有镇痛和抗炎作用。合成了一系列新的1-杂芳基丙烷-2-酮,并评估了其对FAAH的抑制作用。结构-活性关系研究表明,1 H-苯并三唑-1-基,1 H -7-氮杂苯并三唑-1-基,1 H-四唑-1-基和2 H-四唑-2-基对取代的影响最大。抑制力。此外,尝试通过在该丝氨酸反应性基团附近引入屏蔽的烷基取代基来增加这些化合物的酮官能团的有限的代谢稳定性,以降低代谢。
