Various novel methotrexate (MTX) derivatives bearing an indoline moiety were synthesized and tested for biological activities using human peripheral blood mononuclear cell (hPBMC) and human synovial cells (hSC) derived from patients with rheumatoid arthritis (RA). Compounds having potent activity in vitro were further evaluated using an adjuvant arthritis model in vivo. N-[1-(2, 4-Diamino-6-pteridinylmethyl)indoline-5-carbonyl]-L-glutamic acid 2f showed more potent activities than MTX in vitro and in vivo, and N-[1-(2, 4-diamino-6-pteridinylmethyl)-indoline-5-carbonyl]-L-2-aminoadipic acid 2d exhibited fairly good activities in vitro and considerable activity in vivo. Compound 2d was, as expected, not sensitive to folyl-polyglutamate synthetase (FPGS) and did not undergo polyglutamation, a process which may be responsible for a side-effect during MTX therapy.
合成了多种具有吲哚啉基团的甲氨蝶呤(MTX)衍生物,并使用来自类风湿关节炎(RA)患者的人外周血单核细胞(hPBMC)和人滑膜细胞(hSC)测试其生物活性。在体外具有显著活性的化合物在体内进一步通过辅助关节炎模型进行评估。N-[1-(2, 4-二氨基-6-萘啶甲基)吲哚啉-5-羧酰基]-L-谷氨酸2f在体外和体内均表现出比MTX更强的活性,而N-[1-(2, 4-二氨基-6-萘啶甲基)-吲哚啉-5-羧酰基]-L-2-氨基癸二酸2d在体外表现出相当好的活性,在体内也表现出显著活性。化合物2d如预期的那样,对叶酸多谷氨酸合成酶(FPGS)不敏感,且未发生多谷氨酰化,这一过程可能是MTX治疗期间副作用的原因。
