ANTITUMOR AND ANTIVIRAL ANALOGUES

描述：（改编自申请人的摘要）新的核苷和 核苷酸类似物将被制备和研究作为抗病毒和抗肿瘤 剂. 这些化合物将包括（1）亲脂性磷酸盐， 由能够穿透细胞的核酸碱基衍生的丙二烯醇 膜（2）含有环丙烷或环丁烷的核苷类似物 部分和（3）抗HIV剂卡布韦的类似物。 抗肿瘤 将使用小鼠白血病L1210在体外和体内研究活性 培养物和许多其他肿瘤系统，包括实体瘤。 抗病毒作用将在人体试验中进行研究 免疫缺陷病毒（HIV），B肝炎病毒（HBV），人 巨细胞病毒（HCMV）和单纯疱疹1型病毒（HSV-1）。 机制 将研究活性类似物的作用。 将检测腺嘌呤 作为腺苷脱氨酶的底物。

DESCRIPTION: (adapted from Applicant's Abstract) New nucleoside and nucleotide analogs will be prepared and studies as antiviral and antitumor agents. These compounds will include (1) lipophilic phosphates of allenols derived from nucleic acid bases capable of penetrating the cell membrane (2) nucleoside analogues containing cyclopropane or cyclobutane moiety and (3) analogues of the anti-HIV agent carbovir. Antitumor activity will be studies in vitro and in vivo using murine leukemia L1210 cultures and a number of other tumor systems including solid tumors. Antiviral effects will be investigated in assays with human immunodeficiency virus (HIV), hepatitis B virus (HBV), human cytomegalovirus (HCMV), and herpes simplex 1 virus (HSV-1). Mechanisms of action will be studied with the active analogues. Adenine will be tested as substrates for adenosine deaminase.
