Design and Synthesis of 1-Indol-1-yl-propan-2-ones as Inhibitors of Human Cytosolic Phospholipase A2α
摘要:
The synthesis and structure-activity relationship study of a series of 1-indol-1-yl-3-phenoxypropan-2-one inhibitors of cytosolic phospholipase A(2)alpha (cPLA(2)alpha) are described. The compounds were evaluated in a vesicle assay with isolated cPLA(2)alpha and in cellular assays with intact human platelets. Systematic variation led to 3-methylhydrogen 1-[3-(4-decyloxyphenoxy)-2-oxopropyl]indole-3,5-dicarboxylate (57), which revealed the highest activity against the isolated enzyme. With an IC50 value of 4.3 nM in this assay, it is one of the most potent in vitro cPLA(2)alpha inhibitors known today.
A series of derivatives of 1-(4-octylphenoxy)-3-(2H-tetrazol-2-yl)propan-2-one (3) and 1-(4-octylphenoxy)-3-(1H-tetrazol-1-yl)propan-2-one (4) was synthesized and tested for fatty acidamide hydrolase (FAAH) inhibitory potency and phase I metabolic stability. Introduction of certain substituents like 4-chlorophenyl, 4-methoxycarbonylphenyl and carboxyl in position 5 of the tetrazole ring of 3 led to
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。
1-(2-Carboxyindol-5-yloxy)propan-2-ones as inhibitors of human cytosolic phospholipase A2α: Synthesis, biological activity, metabolic stability, and solubility
Indole-5-carboxylic acids with 3-aryloxy-2-oxopropyl residues in position 1 were previously reported to be potent inhibitors of cytosolic phospholipase A(2)alpha (cPLA(2)alpha) isolated from human platelets. In continuation of our attempts to develop novel cPLA(2)alpha inhibitors, a series of structurally related indole-2-carboxylic acids containing 3-aryloxy-2-oxopropoxy residues in position 5 were
1-(5-Carboxy- and 5-carbamoylindol-1-yl)propan-2-ones as inhibitors of human cytosolic phospholipase A2α: Bioisosteric replacement of the carboxylic acid and carboxamide moiety
Indole-5-carboxylic acids and -carboxamides with 3-aryloxy-2-oxopropyl residues in position 1 were previously reported to be potent inhibitors of cytosolic phospholipase A(2)alpha (cPLA(2)alpha) isolated from human platelets. In continuation of our attempts to develop novel cPLA(2)alpha inhibitors, a number of derivatives of these substances characterized by bioisosteric replacement of the carboxylic acid and carboxamide
1-(5-Carboxyindol-1-yl)propan-2-ones as inhibitors of human cytosolic phospholipase A2α: Synthesis and properties of bioisosteric benzimidazole, benzotriazole and indazole analogues
The indole ring systems of the cytosolic phospholipase A2α (cPLA2α) inhibitor 1-[3-(4-octylphenoxy)-2-oxopropyl]indole-5-carboxylic acid (2) and the isomeric 6-carboxylic acid (3) were replaced by benzimidazole, benzotriazole and indazole scaffolds, respectively. The effect of the structural variations on cPLA2α inhibitory potency, metabolic stability and solubility was studied. The lead 2 and the
