New antineoplastic compounds have been isolated, structurally elucidated and synthesized having a general structural formula of:
wherein:
R₁ is OH or OCH₃;
R₂ is H or OCH₃; or R₁R₂ is -OCH₂O-;
R₃ is H or OH; and
R₄ is OH or OCH₃ and wherein the configuration of the double bond in compounds of formula I is cis. These substances have been denominated "combretastatin A-1, -A-2, -A-3, -B-1, -B-2, -B-3 and -B-4". Pharmaceutical preparations containing the substances and methods of treating a host inflicted with a neoplastic growth with the preparation are described.
新的抗肿瘤化合物已被分离、结构阐明和合成,其一般结构式为
其中
R₁ 是 OH 或 OCH₃;
R₂ 是 H 或 OCH₃;或 R₁R₂ 是 -OCH₂O-;
R₃ 是 H 或 OH;以及
R₄ 是 OH 或 OCH₃,其中式 I 化合物中双键的构型为顺式。这些物质被称为 "考布他丁
A-1、-A-2、-A-3、-B-1、-B-2、-B-3 和-B-4"。本文介绍了含有这些物质的药物制剂以及用这些制剂治疗肿瘤生长宿主的方法。
