What is the difference between hydrazine and hydrazide?
Hydrazides in organic chemistry are a class of organic compounds with the formula RNHNH2 where R is acyl (R’CO-), sulfonyl (R’SO2-), or phosphoryl (R’2P(O)-). Unlike hydrazine and alkylhydrazines, hydrazides are nonbasic owing to the inductive influence of the acyl, sulfonyl, or phosphoryl substituent.

Is isoniazid a strong antibiotic?
Isoniazid is an antibacterial recommended for all forms of tuberculosis in which organisms are susceptible. Active tuberculosis must be treated with multiple concomitant anti-tuberculosis medications to prevent the emergence of drug resistance. Isoniazid is recommended as preventive therapy for certain individuals.
Is isoniazid a chemotherapy drug?
The role of individual drugs in first-line chemotherapy of TB[31] is unique. Isoniazid is responsible for the initial kill of about 95% organisms during the first two days of treatment. Its bactericidal role is then replaced by rifampicin and pyrazinamide during the intensive phase.

Where is the carboxy group of isonicotinic acid?
Isonicotinic acid is a pyridinemonocarboxylic acid in which the carboxy group is at position 4 of the pyridine ring. It has a role as a human metabolite and an algal metabolite. It is a conjugate acid of an isonicotinate. Isonicotinic acid is a metabolite of isoniazid.
Which is an isomer of picolinic acid and nicotinic acid?
It is an isomer of picolinic acid and nicotinic acid which has the carboxyl group at the 2- and 3-position respectively compared to the 4-position for isonicotinic acid. Isonicotinic acids is a term loosely used for derivatives of isonicotinic acid. Hydrazide derivatives include isoniazid, iproniazid, and nialamide.
How is isoniazid used to treat Mycobacterium avium complex?
Isoniazid was widely used in the treatment of Mycobacterium avium complex as part of a regimen including rifampicin and ethambutol. Evidence suggests that isoniazid prevents mycolic acid synthesis in M avium complex as in M. tuberculosis and although this is not bactericidal to M. avium complex, it greatly potentiates the effect of rifampicin.
