    • Novel cephem derivatives represented by the general formula ##STR1## wherein Ar is an optionally substituted lipophilic phenyl, naphthyl, benzthiazolyl or pyridyl group; R.sup.1 represents a group of the formula ##STR2## in which R.sup.8 and R.sup.9 are each independently hydrogen, C.sub.1 -C.sub.6 alkyl or (C.sub.1 -C.sub.6)alkoxycarbonyl, said C.sub.1 -C.sub.6 alkyl group being optionally substituted by 1-5 hydroxy or C.sub.1 -C.sub.6 alkoxy groups; m is either 0 or 1; A is a C.sub.2 -C.sub.10 alkyl group optionally substituted by 1-5 hydroxy groups; and R.sup.2 and R.sup.3 are each independently hydrogen or C.sub.1 -C.sub.6 alkyl. The derivatives are gram-positive antibacterial agents especially useful in the treatment of diseases caused by methicillin-resistant Staphylococcus aureus.
    • 由通式 + TR 表示的新型头孢烯衍生物,其中Ar是任选取代的亲脂性苯基,萘基,苯并噻唑基或吡啶基; R 1表示式(VIII)的基团,其中R 8和R 9各自独立地为氢,C 1 -C 6烷基或(C 1 -C 6)烷氧基羰基,所述C 1 -C 6烷基任选被1-5个羟基或C 1 -C 6 烷氧基 m为0或1; A是任选被1-5个羟基取代的C 2 -C 10烷基; 且R 2和R 3各自独立地为氢或C 1 -C 6烷基。 衍生物是革兰氏阳性抗菌剂,特别适用于治疗耐甲氧西林金黄色葡萄球菌引起的疾病。
