neutral amino acid exhibiting weak anticonvulsant activities in vivo. Recently, studies have demonstrated that N-(benzyloxycarbonyl)glycine (1) antagonized seizures superior to glycine in addition to activity in the maximal electroshock (MES) test, a convulsive model where glycine is inactive. In the present study a series of ester and amide derivatives of 1 as well as esters of N-(3-phenylpropanoyl)glycine
甘氨酸是一种小的中性氨基酸,在体内表现出弱的抗惊厥活性。最近,研究表明,在最大电击(MES)测试(一种甘氨酸失活的惊厥模型)中,N-(苄氧羰基)甘氨酸(1)对抗癫痫发作的作用优于甘氨酸。在本研究中,已经制备了一系列的1的酯和酰胺衍生物以及N-(3-苯基丙酰基)甘氨酸的酯(5)。在MES测试以及几种化学诱导的癫痫发作模型中对化合物进行了评估。在所研究的衍生物中,N-(苄氧基羰基)甘氨酸苄酰胺(16)是最有效的化合物,在MES试验中表现出与药物苯妥英相当的抗惊厥活性。腹腔注射后30分钟和3小时测定的中位有效剂量(ED50)为4.8和11.6 mg / kg 行政管理。化合物16还可以在不同的化学诱导模型(例如士的宁,3-巯基丙酸和戊四唑测试)中有效抑制强直性癫痫发作。此外,在150 mg / kg的剂量下,在转子试验中,此处研究的化合物未显示急性神经毒性。结论是,N-(苄氧基羰基)甘氨酸酰胺,特别是16种,是有效的抗惊厥药。

Tripeptide analogs of melanocyte-stimulating hormone release-inhibiting hormone (Pro-Leu-Gly-NH2) as inhibitors of oxotremorine-induced tremor
Fourteen di- and tripeptide analogues of MIF, Pro-Leu-Gly-NH2, have been synthesized and assayed for inhibition of oxotremorine-induced tremor. Replacement of Pro by HCO-Pro or cyclopentanecarboxylic acid gave inactive analogues, while some peptides of the general structure less than Glu-Leu-Gly-NR1R2 were highly active. Thus, R1 = C3H8 and R2 = H gave 4 times the activity of MIF, R1 = I-C3H8 and R2 = H gave 13 times the activity of MIF, and R1 = R2 = CH3 gave 29 times the activity of MIF. cyclo(-Pro-Leu-), Pro-Lys-Gly-NH2, and Pro-Arg-Gly-NH2 had no activity. Apparently, small modifications in the structure of MIF can yield highly active analogues with potential clinical value, e.g., in the treatment of Parkinson's disease or mental depression.
