Diversity-Oriented Synthesis of 1,2,4-Triazols, 1,3,4-Thiadiazols, and 1,3,4-Selenadiazoles from N-Tosylhydrazones

The diversity-oriented synthesis of 1,2,4-triazols, 1,3,4-thiadiazols, and 1,3,4-selenadiazoles from N-tosylhydrazones was developed, and the reactions were general for a wide range of substrates, in which NH2CN, KOCN, KSCN, and KSeCN were used as odorless sources. Two different pathways were proposed, and N-tosylhydrazonoyl chlorides were formed in situ in the presence of NCS.

Discovery of a novel nitroimidazolyl-oxazolidinone hybrid with potent anti Gram-positive activity: Synthesis and antibacterial evaluation

A number of linezolid analogues containing a nitroaryl-1,3,4-thiadiazole moiety, were prepared and evaluated as antibacterial agents against a panel of Gram-positive and Gram-negative bacteria. Among synthesized compounds, nitrofuran analogue 1b exhibited more potent inhibitory activity, with respect to other synthesized compounds and reference drug linezolid. The target compounds were also assessed for their cytotoxic activity against normal mouse fibroblast (NIH/3T3) cells using MTT assay. The results indicated that compound 1c exhibit potent antibacterial activity against Gram-positive bacteria at non-cytotoxic concentrations.

Synthesis and antileishmanial activity of novel 5-(5-nitrofuran-2-y1)-1,3, 4-thiadiazoles with piperazinyl-linked benzamidine substituents

In order to optimize the antileishmanial activity of piperazinyl-linked 5-(5-nitrofuran-2-yl)-1,3,4-thiadiazoles, we synthesized a series of 5-(5-nitrofuran-2-y1)-1,3,4-thiadiazoles with piperazinyl-linked benzamidine substituent as scaffold found in pentamidine related antiprotozoals. The structure of target compounds was confirmed by IR, 1H NMR, 13C NMR and Mass spectral data. All compounds were tested for in vitro activity against the promastigote and amastigote forms of Leishmania major. From the results, we found that the substitution on amidine nitrogen has profound role in the biological activity of these compounds. The 5-nitrofuran-2-yl-1,3,4-thiadiazoles having n-propyl, n-butyl and benzyl side chain on benzamidine (as in compounds 2d, 2e and 2g, respectively) showed very good activity in both forms of promastigote and amastigote. The most active compound was N-propyl-4-(4-(5-(5-nitrofuran-2-yl)-1,3,4-thiadiazol-2-yl) piperazin-1-yl) benzamidine hydrochloride (2d) with IC50 value of 0.08 μM in promastigote model. This compound showed a very low level of toxicity against macrophages (CC50 = 785 μM), with the highest selectivity index (SI = 78.5) among the tested compounds.
