In an attempt to find a new class of antimicrobial agents, a series of thiazole derivatives containing furan moiety 3, 7, 8a,b, 10a-c and 12 were prepared via the reaction of 2-cyano-N-(furan-2-ylmethyl)acetamide (1) with phenyl isothiocyanate and α-halocarbonyl compounds. Also, many bithiazolidinone and pyranothiazole derivatives were synthesized through interaction of thiazolidinone 7 with ap...

i-Motifs are quadruplex DNA structures formed from sequences rich in cytosine and held together by intercalated, hemi-protonated cytosine-cytosine base pairs. These sequences are prevalent in gene promoter regions and may play a role in gene transcription. Targeting these structures with ligands could provide a novel way to target genetic disease but there are very few ligands which have been s...

We have previously proposed that the BlmIV and BlmIII non-ribosomal peptide synthetases are involved in the formation of the bithiazole moiety of the anti-tumor drug bleomycin in Streptomyces verticillus ATCC15003. We report here the identification and characterization of an oxidation domain in BlmIII. The oxidation domain shows local homology to a family of oxidoreductases and is present in al...

Charge transport properties of thiophene, thiazole and thiazolothiazole based oligomers have been studied using electronic structure calculations. The charge transport parameters such as charge transfer integral and site energy are calculated through matrix elements of Kohn-Sham Hamiltonian. The reorganization energy for the presence of excess positive and negative charges and rate of charge tr...
