The Chemotherapy of Experimental Tuberculosis. III. The Synthesis of Thiosemicarbazones and Related Compounds^1,2

A New Type of Dendritic [60]Fullerene–Metallo‐tetraphenylporphyrin Diads (M = Zn, Co)

“…of benzaldehyde and 1 equiv. of 3-(2-hydroxyethoxy)benzaldehyde (7) [18] under high-dilution conditions followed by oxidation with excess DDQ as described by Lindsey [19] and co-workers (Scheme 1). It turned out that by using both aldehyds in equimolar quantities the yield of the desired A3B porphyrin 8 is significantly higher than using a 3:1 ratio.…”

“…Dry solvents were prepared using customary literature procedures. [27] Thin layer chromatography (TLC): Riedel-de Haën silica gel F 254 (7), [18] compounds 8, 9 and 10, [19] and spacer 12 [20] were synthesized according to literature procedures.…”

Antitubercular Substances. III. Nonpyridinoid Heterocyclic Hýdrazides*

“…The situation with respect to substitution in the hydrazide portion of the molecule is somewhat different and, just as with the hydrazine-substituted isonicotinic hydrazides previously described by us (2), the majority of the corresponding furoic hydrazide derivatives (Nos. [18][19][20][21][22][23][24] had an activity in who of the order of magnitude of that of the parent molecule.…”

Synthesis, Molecular Structure and Antibacterial Activity of Benzylmethyl-4-Methyl-3-Thiosemicarbazone

“…It is used as an intermediate in the production of pesticides, rodenticides and anticoagulants [1]. On the other hand, thiosemicarbazones are useful in the medicinal and pharmaceutical fields because of their great significant pharmacological properties such as antibacterial [2] [3] [4], antifungal [2], anti-HIV [5] [6], anticancer [7] [8], antineoplastic [9], anti-inflammatory [10], tuberclostatic [11] and their variable bonding nature. The biological activities of thiosemicarbazones often depend on the parent aldehyde or ketone.…”
