This work deals with the preparation of pyridine-3-carbohydrazide (isoniazid, inh) cocrystals two ?-hydroxycarboxylic acids. The interaction glycolic acid (H2ga) or d,l-mandelic (H2ma) resulted in formation salts composition (inh)·(H2ga) (1) and [Hinh]+[Hma]–·(H2ma) (2) when reacted isoniazid. An N?-(propan-2-ylidene)isonicotinic hydrazide hemihydrate, (pinh)·1/2(H2O) (3), was also prepared by ...
WE shall present here an analysis of the linkage relationhsips among structural genes that control steps of the /3-ketoadipate pathway and two other dissimilatory pathways in a fluorescent pseudomonad, Pseudomonas putida. The convergent branches of the p-ketoadipate pathway (Figure 1 ) , which exists in many taxonomic groups of aerobic bacteria, provide a means for the conversion of certain aro...
FK584[(-)-N-tert-butyl-4,4-diphenyl-2-cyclopentenylamine hydrochloride, (-)-4-HCl], a potential candidate for the treatment of overactive detrusor, was synthesized in a 4-step approach starting with Sharpless oxidation of cyclopentenol 6 (kinetic resolution). This epoxidation is a rare case in that the empirical rule does not work. Regio- and stereoselective introduction of tert-butylamine to t...
This study was aimed to observe that extremely low frequency magnetic field (ELF-MF) may be relevant to changes of major neurotransmitters in rat brain. After the exposure to ELF-MF (60 Hz, 2.0 mT) for 2 or 5 days, we measured the levels of biogenic amines and their metabolites, amino acid neurotransmitters and nitric oxide (NO) in the cortex, striatum, thalamus, cerebellum and hippocampus. The...
