19664921-4	2009	The piperazine ring was shown to be a critical element of the HIV-1 attachment inhibiting pharmacophore, acting as a scaffold to deploy the indole glyoxamide and benzamide in a topographical relationship that complements the binding site on gp120.	Piperazine	4-14	Envelope surface glycoprotein gp160, precursor	Human immunodeficiency virus 1	241-246	
23748247-4	2013	We described an approach that combines molecular docking, molecular dynamics, MM-PBSA calculations and conformational analysis to rationally predict piperazine derivatives binding mode with HIV-1 gp120.	Piperazine	149-159	Envelope surface glycoprotein gp160, precursor	Human immunodeficiency virus 1	196-201
