The SLC51 organic solute transporter family of transporters is a pair heterodimeric proteins which regulate bile salt movements in the small intestine, duct, and liver, as part enterohepatic circulation [2, 5, 1]. OSTα/OSTβ also expressed steroidogenic cells brain adrenal gland, where it may contribute to steroid sulphate movement [6]. Bile acid transport suggested be facilitative independent s...
A Derivatives of 2-thiouracil are characterized by wide spectrum biological activity, which is characteristic most representatives this heterocycles class. In particular, 2-(2-oxo-2-phenylethylthio)-pyrimidin-4(3H)-ones belong to the group non-nucleoside inhibitors HIV-1 reverse transcriptase. The antimalarial properties 2-(2-oxo-2-phenylethylthio)-4-R-pyrimidine derivatives, proved be effec...
A series of 3-Amantadinyl-2-[(4-amino-3-aryl-5-ylthio)-1,2,4-triazolo]methyl)quinazolin-4-one 5(a-i) were prepared by the reaction of 3-Amantadinyl-2-[(4-acetamido-3-aryl-5-ylthio)-1,2,4-triazolo]methyl)quinazolin-4-one 4(a-i) with various 3-aryl-4-acetamido-5-mercapto triazoles. The compounds 5(a-i) biologically evaluated for their antiinflammatory and antibacterial activities.Structures of th...
In order to develop transferable and practical avenues for the assembly of coordination complexes into architectures with specific dimensionality, a strategy utilizing ligands capable of simultaneous metal coordination and self-complementary hydrogen bonding is presented. The three ligands used, 2(1H)-pyrazinone, 4(3H)-pyrimidinone and 4(3H)-quinazolinone, consistently deliver the required synt...

Quinazolinones are a group of fused heterocyclic compounds which have valuable biological properties including cytotoxic, antibacterial and antifungal activities. Thiazole group-containing compounds have been also reported to have a wide range of biological activities such as antitumor, anti-inflammatory, analgesic and antibacterial effects. Due to valuable cytotoxic effects of both thiazole gr...
