  β-Lactam Derivatives as Inhibitors of Human Cytomegalovirus Protease

  摘要：

  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 beta-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 tri- and 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.

  A compound of formula I wherein R1 is hydrogen, methyl, ethyl, methoxy or methylthio; R2 and R3 each independently is hydrogen or lower alkyl; R4 is hydrogen, lower alkyl, methoxy, ethoxy or benzyloxy; R5 is lower alkyl, lower cycloalkyl, (CH2)mC(O)OR6 wherein m is the integer 1 or 2 and R6 is lower alkyl, phenyl optionally substituted; optionally Het or Het(lower alkyl); or R4 and R5 together 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)OR7 wherein R7 is 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 R2 and R3 each is hydrogen; or a therapeutically acceptable acid addition salt thereof which compound is useful in the treatment of HCMV infections.

  式I的化合物中，其中R1为氢、甲基、乙基、甲氧基或甲硫基；R2和R3各自独立地为氢或较低的烷基；R4为氢、较低的烷基、甲氧基、乙氧基或苄氧基；R5为较低的烷基、较低的环烷基、(CH2)mC(O)OR6，其中m是整数1或2，R6为较低的烷基、苯基可选择地取代；可选择地为Het或Het(较低的烷基)；或者R4和R5与它们连接的氮原子一起形成一个含氮环，该环可选择地取代为C(O)O-苄基或苯基，该苯基可选择地取代为C(O)OR7，其中R7为较低的烷基或(较低的烷基)苯基；Z为较低的烷基或可选择地取代的苯基或Het；但是当Z为(CH2)p-(Het)时，那么R2和R3各自为氢；或其治疗上可接受的酸盐，该化合物在HCMV感染的治疗中有用。
