  Relationships between structure, antibacterial activity, serum stability, pharmacokinetics and efficacy in 3-(heteroarylthio)cephems. Discovery of RWJ-333441 (MC-04,546)

  摘要：

  SAR studies in a series of related 3-(heteroarylthio)cephems determined that a relatively high chemical reactivity of the beta-lactam ring, modulated by electronic effects of substituents at C-3 and C-7, is necessary to achieve high in vitro activity against methicillin-resistant Staphylococcus aureus (MRSA). Such high reactivity results in lowered hydrolytic stability and concomitantly increases susceptibility to beta-lactam ring opening mediated by serum enzymes. Therefore, optimization of anti-MRSA activity versus stability toward serum-mediated degradation required a fine balance of substituent effects. Serum stability studies (measured as percentage of parent drug degraded after 60 min incubation) revealed up to 80-fold difference in degradation rate in a series of closely related (3-heteroarylthio)cephems. Of the compounds evaluated, RWJ-333441 (MC-04,546) possessed the best balance of serum stability (6% degradation after 60 min incubation) and in vitro activity versus MRSA (S. aureus COL MIC-I mug/mL). Accordingly, RWJ-333441 displayed excellent in vivo efficacy versus methicillin-susceptible Staphylococcus aureus (MSSA, ED50=0.39 mg/kg in mouse sepsis model with S. aureus Smith) and good pharmacokinetic properties in the rat (Cl-total=0.39 L/h/kg).

  The present invention relates to a cephem prodrug having formula III or formula IV: or a pharmaceutically acceptable salt thereof, wherein R′1 is selected from the group consisting of hydrogen and —C(O)CH(NH2)CH3 and R′2 is selected from the group consisting of hydrogen and an acyl group that is cleaved by an enzyme found in mammals, with the proviso that, when either R′1 or R′2 is hydrogen, the other is not. A, B, L, G, E, and J are each independently nitrogen or carbon such that the respective rings are selected from the group consisting of provided that the group —CH2—S—CH2CH2NHR′2 is attached only to a carbon atom of said heterocyclic group, and Q is selected from the group consisting of nitrogen and —CX, wherein X is selected from the group consisting of hydrogen and chlorine.

  本发明涉及具有III式或IV式的头孢菌素前药：或其药用可接受的盐，其中R′1选自由氢和—C(O)CH(NH2)CH3的群组，R′2选自由氢和在哺乳动物中发现的一种酶可水解的酰基团，但条件是当R′1或R′2中的一个是氢时，另一个不是。A、B、L、G、E和J分别独立地为氮或碳，使得相应的环被选自的群组选中，前提是群组—CH2—S—CH2CH2NHR′2仅连接到所述杂环基团的一个碳原子上，Q选自氮和—CX的群组，其中X选自氢和氯。
