    • The present invention relates to esters of 3-demethylthiocolchicine and N-acyl analogs thereof having the following formula: ##STR1## wherein R is O-CO-alkyl, O-CO-CH.sub.2 Oalkyl, O-CO-Phenyl, O-COOalkyl; the alkyl group having from 1 to 4 carbon atoms and the Ac group representing acetyl and its higher homologs, benzoyl, alkoxyacetyl, or haloacetyl.The invention further relates to processes for preparing these ester compounds, pharmaceutical compositions thereof and methods for treating diseases such as gout, Mediterranean fever and liver disorders.
    • 本发明涉及3-脱甲基硫代秋水仙碱及其N-酰基类似物的具有下式的酯:其中R是O-CO-烷基,O-CO-CH2O烷基,O-CO-苯基,O-COO烷基; 具有1至4个碳原子的烷基和Ac基团代表乙酰基及其较高同系物,苯甲酰基,烷氧基乙酰基或卤代乙酰基。 本发明进一步涉及制备这些酯化合物的方法,其药物组合物和治疗诸如痛风,地中海热和肝病等疾病的方法。

    • The present invention consists of derivatives of colchicine and thiocolchicine which are carbamates of the same and are illustrated by the formula below: ##STR1## where either X.sub.1 or X.sub.2 is a hydroxy group and the other a lower alkoxy group and R.sub.1 can be H or an alkyl, R.sub.2 an alkyl, alkenyl or aryl which may be substituted and R.sub.3 is either OCH.sub.3 or SCH.sub.3 ; alkyl and alkoxy=C.sub.1 -C.sub.6 ; aryl=monoaryl.These compounds are not only new but have exhibited antitumor activity binding to tubulin protein and tests against P388 lymphocytic leukemia and also active against gouty arthritis. Further, they are far less toxic than colchicine.
    • 本发明由秋水仙素和硫代秋水仙素的衍生物组成,它们是氨基甲酸酯的衍生物,它们由下式表示:其中X1或X2是羟基,另一个是低级烷氧基,R1可以是H或 烷基,R 2为可被取代的烷基,烯基或芳基,R 3为OCH 3或SCH 3; 烷基和烷氧基= C1-C6; 芳基=单芳基。 这些化合物不仅是新的,而且具有结合微管蛋白的抗肿瘤活性和针对P388淋巴细胞性白血病的抗肿瘤活性,并且对抗痛风性关节炎也是有效的。 此外,它们比秋水仙碱毒性低得多。
