Ala-hydroxy vitamin D, derivative of the formula:
where R, is a hydroxyl group, an amino group or the group: OR' (where R' is a lower alkyl group having 1 to 7 carbon atoms that may or may not be substituted by a hydroxyl group, a halogen atom, a cyano group, a lower alkoxy group having 1 to 3 carbon atoms, an amino group, or an acylamino group); R2 is a hydrogen atom or a hydroxyl group), and a process for preparing the same are disclosed.
The compounds represented by the formula above are effective for calcium control and for induction of differentiation in tumor cells and, therefore, are useful as antitumor agents and a medicine for treating calcium dysbolism-caused diseases.
本发明公开了阿拉羟基维生素D的衍生物的化学式,其中R是一个羟基,一个氨基或者一个基团:OR'(其中R'是一个有1到7个碳原子的低级烷基基团,可以或不可以被一个羟基,卤素原子,氰基,一个有1到3个碳原子的低级烷氧基基团,一个氨基或者一个酰胺基取代);R2是一个氢原子或者一个羟基。本发明还公开了制备该化合物的方法。上述化学式所代表的化合物在钙控制和肿瘤细胞分化诱导方面具有有效性,因此,它们可以作为抗肿瘤剂和治疗钙代谢失调疾病的药物。
