Azetidinone derivatives for the treatment of HCMV infections

A compound of formula I wherein R1is hydrogen, methyl, ethyl, methoxy or methylthio; R2and R3each independently is hydrogen or lower alkyl; R4is hydrogen, lower alkyl, methoxy, ethoxy or benzyloxy; R5is lower alkyl, lower cycloalkyl, (CH2)mC(O)OR6wherein m is the integer 1 or 2 and R6is lower alkyl, phenyl optionally substituted; optionally Het or Het(lower alkyl); or R4and R5together with the nitrogen atom to which they are attached form a nitrogen containing ring optionally substituted with C(O)O-benzyl or with phenyl optionally substituted with C(O)OR7wherein R7is lower alkyl or (lower alkyl)phenyl; and Z is lower alkyl or optionally substituted phenyl or Het; with the proviso that when Z is (CH2)p-(Het), then R2and R3each is hydrogen; or a therapeutically acceptable acid addition salt thereof which compound is useful in the treatment of HCMV infections.

β-lactam derivatives as inhibitors of human cytomegalovirus protease

The development of novel monobactam inhibitors of HCMV protease incorporating a carbon side chain at C-4 and a urea function at N-1 is described. Substitution with small groups at the C-3 position of the β- lactam ring gave an increase in enzymatic activity and in stability; however, a lack of selectivity against other serine proteases was noted. The use of both triand tetrasubstituted urea functionalities gave effective inhibitors of HCMV protease. Benzyl substitution of the urea moiety was beneficial, especially when strong electron-withdrawing groups where attached at the para position. Modest antiviral activity was found in a plaque reduction assay.
