, p. 501 - 502 (1986)
Five new 2-methyl-3--4(3H)-quinazolinones have been synthesized.Three of them were tested for their antifungal activity against agricultural fungi by the food poison technique and the activity was compared with that of Dithan M-45.

A facile and sustainable approach for the amination of benzothiazoles with KSeCN using iodine as the catalyst in water has been disclosed under transition-metal free conditions. The reaction proceeded smoothly to afford various primary 2-amino benzothiazoles in up to 96% yield. A series of control experiments were performed, suggesting a ring-opening mechanism was involved via a radical process. This protocol provides efficient synthesis of primary 2-aminobenzothiazoles

Abstract: The condensation of 2-amino-1,3-thiazolium perchlorates and their benzo analogs with trifluoro-acetyl-acetone in acetic acid afforded the corresponding [1,3]thiazolo[3,2-a]pyrimidinium, pyrimido[2,1-b][1,3]benzothiazolium, and naphtho[2′,1′:4,5][1,3]thiazolo[3,2-a]pyrimidinium salts as a single isomer in which the trifluoromethyl group is located in the γ-position with respect to the bridgehead nitrogen atom. The structure of the synthesized compounds was confirmed by 1H NMR spectra and elemental analyses.

Monoamine oxidases (MAO) are enzymes that catalyze the oxidative deamination of monoamines such as dopamine, noradrenaline, adrenaline, and serotonin. Recent studies have shown that numerous benzothiazole derivatives exhibit hMAO inhibitory activity in the micromolar concentration range. In this study, a novel series of benzothiazole-thiadiazole (5a-5l) was synthesized and characterized their chemical structures by 1H-NMR, 13C-NMR, and Mass spectroscopy. These compounds were evaluated as inhibitors for types A and B MAO enzymes. Compounds 5f and 5l were the most active derivatives in the series with an IC50 values of 0.107 ± 0.003 and 0.128 ± 0.004, respectively. Furthermore, cytotoxicity of compounds 5f and 5l were investigated and found as non-cytotoxic.
