Studies on Antitubercular Compounds. X. Condensation Products of Aldehydes and Acid Hydrazides of Pyridine Group

Studies on the Antitubercular Compounds (XII) Effect on Antitubercular Activity of Acid Hydrazide by the Condensation with Aldehyde Shichiro

Design, synthesis and antitubercular activity of certain nicotinic Acid hydrazides.

Three series of 6-aryl-2-methylnicotinohydrazides 4a-i, N'-arylidene-6-(4-bromophenyl)-2-methylnicotino hydrazides 7a-f, and N'-(un/substituted 2-oxoindolin-3-ylidene)-6-(4-fluorophenyl)-2-methylnicotinohydrazides 8a-c were synthesized and evaluated for their potential in vitro antimycobacterial activity against M. tuberculosis. The results showed that isatin hydrazides 8a-c are remarkably more...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Kinetic Studies of Condensation of Aromatic Aldehydes with Meldrum’s Acid

The condensation reaction of Meldrum’s acid with aromatic aldehydes in the presence of a catalyst has been investigated spectrophotometrically at 25Ð50 ∞C. The reaction follows overall second order kinetics, first order in each of the reactants. Electron-withdrawing groups accelerate and electron-releasing groups retard the rate of condensation. From the dependence of the rate constants on temp...
