N-Hydroxy-5-norbornene-2,3-dicarboximide Chemical Properties,Uses,Production

Description

N-Hydroxy-5-norbornene-2,3-dicarboximide (NHD) is a compound that has antiviral activity and is used to treat HIV infections. It inhibits the reverse transcriptase enzyme in the virus, which blocks the synthesis of viral DNA. The ferroelectric properties of NHD were first observed by observing changes in its melting point when mixed with water. This property makes it useful for diagnosis purposes. In animal studies, a dose of 5 mg/kg was found to be effective against cancer cells and the drug showed no toxicity in humans at doses up to 500 mg/day. The optimal reaction conditions for NHD are pH 6 and temperature 45 degrees Celsius.

Chemical Properties

white to off-white crystalline powder

Uses

It decreases racemization in peptide synthesis and inhibits formation of N-acylureas.

Uses

Inhibits racemization in peptide synthesis using DCC as condensing agent.

Uses

N-Hydroxy-5-norbornene-2,3-dicarboximide(HONB) is used in solution-phase peptide synthesis. Used in the synthesis of enkephalin analogs.

Purification Methods

Dissolve the imide in CHCl3, filter, evaporate and recrystallise from EtOAc. IR (nujol): max 1695, 1710 and 1770 (C=O), and 3100 (OH) cm-1. The O-acetyl derivative has m 113-114o (from EtOH) with IR bands at max 1730, 1770 and 1815 cm-1 only, and the O-benzoyl derivative has m 143-144o (from propan-2-ol or *C6H6).
