increased levels of cyclic nucleotides (cGMP and cAMP) in enterocytes trigger intracellular mechanisms of ion and fluid secretion into the lumen, causing secretory diarrhea. Twelve novel pyridopyrimidines derived from 5‐(3,5‐bistrifluoromethylphenyl)‐1,3‐dimethyl‐5,11‐dihydro‐1H‐indeno[2,1 : 5,6]pyrido[2,3‐d]pyrimidine‐2,4,6‐trione (FPIPP) were synthesized and evaluated on intracellular cyclic nucleotide accumulation
肠上皮细胞中环状核苷酸(cGMP和cAMP)水平的升高触发了细胞内离子和液体分泌进入管腔的细胞内机制,从而导致分泌性腹泻。衍生自5-(3,5-双三氟甲基苯基)-1,3-二甲基-5,11-二氢-1H-茚并[2,1:5,6]吡啶基[2,3-d]嘧啶-2的十二个新颖的嘧啶嘧啶合成了4,4,6-三酮(FPIPP)并评估了细胞内环核苷酸的积累。所有化合物均对环状核苷酸基础水平或预收缩主动脉环均无影响。分别通过MTT(3-(4,5-二甲基噻唑-2-基)-2-溴5-二苯基四唑鎓)和LDH(乳酸脱氢酶)检测评估的T84细胞中的代谢活性和生存力不受影响。与化合物(50μM)一起孵育。化合物VI几乎消除了STa毒素在T834细胞中诱导的cGMP积累(抑制94%),并显着降低了Juskat细胞中佛司可林诱导的cAMP积累(69%)。化合物VI在兔腹泻的体内模型中具有活性。这些结果促使我们对肠道组织进行显微组织病
