A series of arylthioureas (1), aromatic aldehyde thiosemicarbazones (2) and 5-aryl-2-furfuraldehyde thiosemicarbazones (3) were condensed with 2,4-dichloro-5-fluorophenacyl bromide to yield respective arylaminothiazoles, arylidene/5-aryl-2-furfurylidene hydrazinothiazoles (4). The newly synthesized compounds were characterized by IR, 1H-NMR and mass spectral studies. These compounds were also screened
Two series of compounds carrying 3-amino-1,2,4-triazole scaffold were synthesized and evaluated for their anticancer activity against a panel of cancer cell lines using XTT assay. The 1,2,4-triazole synthesis was revisited for the first series of pyridyl derivatives. The biological results revealed the efficiency of the 3-amino-1,2,4-triazole core that could not be replaced and a clear beneficial effect

An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.
