Structure–activity relationship study of phenylpyrazole derivatives as a novel class of anti-HIV agents
摘要:
The structure-activity relationship of phenylpyrazole derivative 1 was investigated for the development of novel anti-HIV agents. Initial efforts revealed that the diazenyl group can be replaced by an aminomethylene group. In addition, we synthesized various derivatives by the reductive amination of benzaldehydes with 5-aminopyrazoles and carried out parallel structural optimization on the benzyl group and the pyrazole ring. This optimization led to a six-fold more potent derivative 32j than the lead compound 1, and this derivative has a 3',4'-dichloro-(1,1'-biphenyl)-3-yl group. (C) 2013 Elsevier Ltd.

Piperidine derivatives of formula ##STR1## can be prepared by reacting 4-amino-piperidine with for example enolic ethers. The compounds obtained may be used as stabilizers.
