Abstract:

A series of pyrazinethiols and pyrimidinethiols with phenyl substituents have been prepared and converted into their carbamoylmethylthio, 2-dimethylaminoethylthio and 2-aminoethylthio derivatives. Similar derivatives of pyrazine-2,3- and -2,6-dithiol were also prepared together with N,N-dimethyl-2-(1′- and 2′- naphthyloxy)ethylamine. As amplifiers of phleomycin these compounds showed moderate two-to- three-star activity.

Abstract:

The preparation of a number of pyrimidinethiols and (substituted) thiopyrimidines has been carried out. The reaction of 5-acetylamino-2-aminopyrimidine-4,6-diol with phosphorus penta -sulfide in pyridine gave 5-amino-2-methylthiazolo[5,4-d]pyrimidine-7-thiol which was used to prepare several additional novel pyrimidine derivatives. Hydrolysis of the 4-carboxymethylthio derivative by using 5M hydrochloric acid gave 2,5-diamino-6-mercaptopyrimidin-4-ol hy -drochloride whilst hydrolysis of 2-methyl-7-methylthiothiazolo[5,4-d]pyrimidin-5-amine gave the corresponding 4-hydroxy derivative.

Abstract:

A number of 2-arenecarbonylmethylthiopyrimidin-4(1H)-ones has been synthesized. Those having H, Me or Pr as a 6-substituent undergo ready sulfur extrusion on heating in diphenyl ether to give 2- ( arenecarbonylmethylene )-2,3-dihydropyrimidin-4(1H)-ones, but those that have a 6-amino substituent or a 5-methyl substituent did not undergo this reaction under these conditions. Some other arenecarbonylmethylthiopyrimidines also did not undergo sulfur extrusion under these conditions. The methylenepyrimidinones formed from 6-methyl-(and 6-propyl-) pyrimidines show two 1H n.m.r. signals for both the

Abstract:

In the title compound, C4H6N4S·0.5H2O, there are two independent pyrimidinethione units, both of which lie across mirror planes in the space groupCmca. Hence, the H atoms bonded to the ring N atoms in each molecule are disordered over two symmetry-related sites, each having an occupancy of 0.5. The water molecule lies across a twofold rotation axis parallel to [010]. The molecular components of (I) are linked by seven independent hydrogen bonds, of N—H...N, N—H...S, N—H...O and O—H...S types. A combination of disordered N—H...N hydrogen bonds and ordered N—H...S hydrogen bonds links the pyrimi

Abstract:

Ultraviolet (UV)-protective and antimicrobial cotton fabrics are necessary for the protection of our skin. In this article, a pyrimidinethione hydrazide (PTH) derivative ligand was complexed with Mn, Co, Ni, Cu, Zn, and Cd as divalent metals and Fe and Cr as trivalent metals to prepare highly antimicrobial and UV-blocking metal–pyrimidinethione hydrazide-modified cotton fabrics (M-PTH-C). The cotton sample treated (M-PTH) was found to show improved efficiency over pyrimidinethione hydrazide-modified cotton (PTH-C). Cadmium-PTH-C showed the highest performance of antimicrobial action against St
