Description
Rescriptor was launched in the US for HIV positive individuals. It can be prepared in seven steps from 2-chloro-3-nitropyridine and piperazine. Rescriptor is a member of the bis(heteroaryl)piperazine (BHAP) class of non-nucleoside HIV-1 reverse transcriptase inhibitors (NNRTIs) of which it is a second generation drug. It acts exclusively as an allosteric mixed inhibitor of both RNA- and DNA-directed polymerase domains of RT and has a much higher binding affintiy for the enzymesubstrate complex than for the free enzyme. Rescriptor does not inhibit RNase H activity of RT. It prevented the spread of HIV significantly longer than AZT. Development of resistance to Rescriptor can occur, however the mutated strain becomes more vulnerable to other members of the NNRTIs. It is metabolized in the liver by CYP3A.

Uses
A bisheteroarylpiperazine (BHAP) reverse transcriptase inhibitor
Definition
ChEBI: The monomethanesulfonic acid salt of delavirdine, a non-nucleoside reverse transcriptase inhibitor with activity specific for HIV-1. Viral resistance emerges rapidly when delavirdine is used alone, so it is therefore used (as the methanesulfonic acid salt) with other antiretrovirals for combination therapy of HIV infection.
