A series of trisubstituted pyrimidines were synthesized to improve aqueous solubility of our first TRPV1 clinical candidate (1; AMG 517), while maintaining potent TRPV1 inhibitory activity. Structure-activity and structure-solubility studies led to the identification of compound 26. The aqueous solubility of 26 (>or=200microg/mL, 0.01 HCl; 6.7microg/mL, phosphate buffered saline (PBS); 150microg/mL
合成了一系列三取代的嘧啶,以改善我们第一个TRPV1临床候选药物(1; AMG 517)的水溶性,同时保持有效的TRPV1抑制活性。结构活性和结构溶解度研究导致了化合物26的鉴定。26的水溶解度(≥200 microg / mL,0.01 HCl; 6.7microg / mL,磷酸盐缓冲盐水(PBS); 150microg / mL,禁食-状态模拟肠液(SIF))明显改善了1.。此外,发现化合物26具有口服生物利用度(大鼠F(口服)= 24%),并且具有有效的TRPV1拮抗剂活性(辣椒素IC(50)= 1.5nM )相当于1。
