Abstract:
The understanding of intermolecular interactions is a key objective of crystal engineering in order to exploit the derived knowledge for the rational design of new molecular solids with tailored physical and chemical properties. The tools and theories of crystal engineering are indispensable for the rational design of (pharmaceutical) cocrystals. The results of cocrystallization experiments of the antithyroid drug 6-propyl-2-thiouracil (PTU) with 2,4-diaminopyrimidine (DAPY), and of 6-methoxymethyl-2-thiouracil (MOMTU) with DAPY and 2,4,6-triaminopyrimidine (TAPY), respectively, are reported.

Abstract:
The results of seven cocrystallization experiments of the antithyroid drug 6-methyl-2-thiouracil (MTU), C5H6N2OS, with 2,4-diaminopyrimidine, 2,4,6-triaminopyrimidine and 6-amino-3H-isocytosine (viz.2,6-diamino-3H-pyrimidin-4-one) are reported. MTU features anADA(A= acceptor andD= donor) hydrogen-bonding site, while the three coformers show complementaryDADhydrogen-bonding sites and therefore should be capable of forming anADA/DADN—H...O/N—H...N/N—H...S synthon with MTU. The experiments yielded one cocrystal and six cocrystal solvates, namely 6-methyl-2-thiouracil–2,4-diaminopyrimidine–1-methy

Abstract:
Synthesis and antimicrobial evaluation of some 6-aryl-5-cyano-2-thiouracil derivativesA series of 6-aryl-5-cyano-2-thiouracil derivatives (1a-d) was synthesized by the reaction of ethyl cyanoacetate with thiourea and aldehydes. These products were used as intermediate compounds for the synthesis of a number of thiouracil derivatives (2a-dto10a-d). All compounds were screened for antibacterial and antifungal activities. Some of the prepared compounds, 6-(4-fluorophenyl)-4-oxo-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxamide (2a), 4-oxo-2-thioxo-6-(3,4,5-trimethoxyphenyl)-1,2,3,4-tetrahydropy

Abstract:
The oxirane ring opening of 3-[(benzyloxy)methyl]-7-oxabicyclo[4.1.0]heptane with sodium salt of diethyl malonate followed by treatment with TsOH gave (3aR*,6R*,7aS*)-6-[(benzyloxy)methyl]hexahydro-1-benzofuran-2(3H)-one (3a) and (3aR*,5R*,7aS*)-5-[(benzyloxy)methyl]hexahydro-1-benzofuran-2(3H)-one (3b). Lactones 3a and 3b were formylated and then treated with thiourea or guanidine to give, after deprotection, racemic 5-[2-hydroxy-4- and 2-hydroxy-5-(hydroxymethyl)cyclohexyl]-2-thiouracil (5a and 5b) or -isocytosine (12a and 12b).

Abstract:
Protein translocation is essential for bacterial survival and the most important translocation mechanism in bacteria is the secretion (Sec) pathway. Thus targeting Sec pathway is a promising strategy for developing novel antibacterial therapeutics. We report the design, syntheses, mechanistic studies and structure-activity relationship studies using HQSAR and 3-D QSAR Topomer CoMFA analyses of 4-oxo-5-cyano thiouracil derivatives. In summary, introduction of polar group such as –N3 and linker groups such as –CH2-O- enhanced the potency as well as logP and logS several fold. We also report the
