The mechanism of antitumor action of 1-(2-chloroethyl)-1-nitroso-3-(3-pyridylmethyl) urea Narom-oxide (I) was chemically studied using several biological model compounds. Compound I reacted with piperidine (a model compound for nucleic acid bases) in acetone to form 1-(2-chloroethyl) piperidine, 1, 2-bispiperidinoethane and 1, 1-pentamethylene-3-(3-pyridylmethyl) urea Narom-oxide (III). Moreover, 1-(2-chloroethyl) piperidine reacted with piperidine in acetone to form 1, 2-bispiperidinoethane. Compound I reacted with Nα-acetyl-L-lysine in weakly alkaline conditions and with N-acetyl-DL-penicillamine in acidic methanol (both are model compounds for enzyme proteins having NH2 and SH groups) to form 1-(5-acetylamino-5-carboxy-1-pentamethylene)-3-(3-pyridylmethyl) urea Narom-oxide and N-acetyl-S-nitroso-DL-penicillamine, respectively. Based on these chemical data, a possible antitumor action mechanism of compound I is discussed.
利用几种生物模型化合物对 1-(2-氯乙基)-1-亚硝基-3-(3-吡啶基甲基)脲 Narom-oxide (I) 的抗肿瘤作用机制进行了化学研究。化合物 I 与哌啶(一种核酸碱基模型化合物)在丙酮中反应生成 1-(2-氯乙基)哌啶、1, 2-双哌啶乙烷和 1, 1-五亚甲基-3-(3-吡啶基甲基)脲纳罗姆氧化物(III)。此外,1-(2-氯乙基)哌啶与丙酮中的哌啶反应生成 1,2-双哌啶乙烷。化合物 I 在弱碱性条件下与 Nα- 乙酰基-L-赖氨酸反应,在酸性甲醇中与 N-乙酰基-DL-青霉胺反应(两者都是具有 NH2 和 SH 基团的酶蛋白模型化合物),分别生成 1-(5-乙酰氨基-5-羧基-1-五亚甲基)-3-(3-吡啶基甲基)脲 Narom-oxide 和 N-乙酰基-S-亚硝基-DL-青霉胺。根据这些化学数据,讨论了化合物 I 可能的抗肿瘤作用机制。
