The approach will help design and synthesis of luminescent complexes as promising materials.

Isoniazid or isonicotinic acid hydrazine ( INH) is a potent anti- synthesis of Mycobacterium tuberculosi, thus inhibiting its cell wall synthesis [1] glucose, found in citrus, soft fruits and leafy green vegetables [10].Antibiotic susceptibility profile of Mycobacterium avium7 Aug 2012 Decreased susceptibility to the protein synthesis . Please note that Sigma-Aldrich provides this product to early discovery researchers as part of a collection of rare and unique . Isonicotinic acid is a pyridine derivative with pyridine and carboxyl as an active group that can make coordination with metal ions on bioMOF assemblies. This is a question our experts keep getting from time to time. All Photos (1) Linear Formula: C 15 H 13 N 3 O. CAS Number: 1320397-26-9. Compound 9h showed comparable in vitro activity (MIC) to isoniazid against M. tuberculosis H37R Synthesis of [ 14 C] labeled 2-methoxypyrimidine-5-carboxylic acid.
