This invention provides a penicillin derivative of the formula
wherein R1 and R2 are the same or different and represent hydrogen, C1-6 alkyl, C1-6 hydroxyalkyl, C3-9 acyloxyalkyl, C8-13 benzyloxyalkyl, C2-7 alkoxyalkyl, C2-7 alkoxycarbonyl, C3-8 alkenyloxycarbonyl, C3-8 alkynyloxycarbonyl, phenyl, amino, formyl, trifluoromethyl, C2-6 acyl, carbamoyl, C2-7 alkylcarbamoyl, benzyloxycarbonylamino, C2-7 alkoxycarbonylamino; and R3 is hydrogen, a group for forming a pharmaceutically acceptable salt, or a penicillin carboxyl protecting group, with the proviso that both of R1 and R2 are not hydrogen or C2-7 alkoxycarbonyl at the same time and that when one of R1 and R2 is hydrogen, the other is not C2-7 alkoxycarbonyl, or a pharmaceutically acceptable acid addition salt, process for preparing the derivative, and a pharmaceutical composition containing the derivative.
C2-7烷氧基羰基、C3-8烯氧基羰基、C3-8炔氧基羰基、苯基、氨基、甲酰基、三氟甲基、C2-6酰基、氨基甲酰基、C2-7烷基氨基甲酰基、苄氧羰基氨基、C2-7烷氧羰基氨基;和 R3 是氢、形成药学上可接受的盐的基团或青霉素羧基保护基团,但 R1 和 R2 不能同时是氢或 C2-7 烷氧羰基,当 R1 和 R2 中的一个是氢时,另一个不是 C2-7 烷氧羰基,或药学上可接受的酸加成盐,制备该衍生物的工艺,以及含有该衍生物的药物组合物。
