Synthesis, docking, ADMET prediction, cytotoxicity and antimicrobial activity of oxathiadiazole derivatives. Comput Biol Chem 2018; 77:226-239.

Abstract
A series of molecules bearing oxathiadiazole, a five membered heterocyclic ring has been designed, synthesized and screened for antimicrobial activity. Molecules, 1a, 1b, 1d, 3a-b and 4a-b were found to be highly active (MIC value upto 1.5 μg/mL) against different human pathogens, namely S. aureus, B. cerus, P. aeruginosa and E. coli. Some of the compounds, 1a, 1b and 1d have also shown the antifungal activity (MIC value upto 6.2 μg/mL) against Candida albicans, Candida glubrate and Candida crusei. During in vitro cytotoxicity study, the oxathiadiazole derivatives showed less toxicity than the reference used against PBM, CEM and Vero (African green monkey kidney) cell lines. Docking studies suggested that all designed ligands interacted well within active site of PDF enzyme (PDB ID: 1G2A). Oxathiadiazole ring of all ligands formed H-bond with amino acid Leu91 at a distance ranging between 2.5-2.8 Å and also exhibited π - + and π - π interactions with amino acid residues Arg97 and His132, respectively. In silico ADMET evaluations of compounds showed more than 90% intestinal absorption for all compounds except 4b (87.45%), which too was greater than the reference drugs sulfamethoxazole (76.46%) and chloramphenicol (69.94%). TOPKAT results also supported the lower cytotoxicity of all compounds.

Abstract
A series of newer 1,2,4-triazole-3-thiol derivatives 5(a-m) and 6(a-i) containing a triazole fused with pyrazine moiety of pharmacological significance have been synthesized. All the synthesized compounds were screened for their in vitro antileishmanial and antioxidant activities. Compounds 5f (IC50=79.0µM) and 6f (IC50=79.0µM) were shown significant antileishmanial activity when compared with standard sodium stibogluconate (IC50=490.0µM). Compounds 5b (IC50=13.96µM) and 6b (IC50=13.96µM) showed significant antioxidant activity. After performing molecular docking study and analyzing overall binding modes it was found that the synthesized compounds had potential to inhibit L. donovani pteridine reductase 1 enzyme. In silico ADME and metabolic site prediction studies were also held out to set an effective lead candidate for the future antileishmanial and antibacterial drug discovery initiatives.

Abstract
The title compound, C13H16N4O3S2·H2O, crystallizes in a ‘folded’ conformation with the ester group lying over the carbamoyl moiety, with one solvent water molecule. The molecular conformation is stabilized by an intramolecular C—H⋯O hydrogen bond, and an N—H⋯O hydrogen-bonding interaction involving the lattice water molecule. The packing involves N—H⋯N, N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds and consists of tilted layers running approximately parallel to the c axis, with the ester groups on the outer sides of the layers and with channels running parallel to (101).

Abstract
We report the synthesis and screening of forty novel 4-nitropyrrole-semicarbazide conjugates inspired from the reported bio-potential of bromopyrrole alkaloids and semicarbazide derivatives for antimicrobial activity. Herein, hybrids 5k-5o, 5r, 5s and 5t displayed four-fold increased activity (MIC=0.39 μg/mL) against Escherichia coli compared to standard ciprofloxacin. Eight hybrids, 5k-5o and 5r-5t displayed equal antibacterial activity (MIC=1.56 μg/mL) against Klebsiella pneumonia compared to standard ciprofloxacin. Hybrid, 5k-5o (MIC=0.195 μg/mL) displayed highly potent antibacterial activity against MSSA as compared to standard ciprofloxacin. Eight-fold superior activity was observed for four hybrids 5k-5m and 5o (MIC=0.39 μg/mL) against MRSA. Further, nine hybrids displayed four-fold superior antifungal activity (MIC=0.78 μg/mL) compared to standard Amphotericin B. Encouraging MICs of these hybrids recognize them as promising leads for development of potential antimicrobial drugs.

Abstract
Investigation of tautomerism and transition states in a derivative of 1,3,4-oxadiazole (A, B, C and D) in the gas phase and in solution and in a micro hydrated environment with 1-3 water molecules was performed by calculations at the DFT-B3LYP/6-311++G(d,p) level of theory. The solvent effect is taken into account via the self-consistent reaction field (SCRF) method. The geometries of four possible tautomers of 5-amino-1,3,4-oxadiazole-2(3H)-one were optimized in the gas phase and solution with polarized continuum model (PCM). It was found that in the gas phase and different solvents, A and C tautomers are the most stable and unstable forms, respectively. The results show that the tautomeric interconversion C to D has the lowest Gibbs free energy changes and so the highest equilibrium constant in the gas phase and solution. The equilibrium and rate constants of intermolecular tautomerism in the absence and presence of 1-3 molecules of water were also calculated. The calculated results show that the presence of water molecules considerably reduces the barrier energy of the various reactions. Therefore, this water-assisted tautomerism can be performed fast, especially, with the assistance of two molecules of water.

The molar conductance measurements of all the complexes in DMF solution correspond to non-electrolytic nature. All complexes were of the high-spin type and found to have six-coordinate octahedral geometry except the Cu(II) complexes which were four coordinate, square planar and U- and La-atoms in the uranyl and lanthanide have a pentagonal bipyramidal coordination sphere. The antimicrobial activity of these complexes has been screened against two gram-positive and two gram-negative bacteria. Antifungal activity against two different fungi has been evaluated and compared with reference drug sparfloxacin. All the binary and ternary complexes showed remarkable potential antimicrobial activity higher than the recommended standard agents. Ni(II)- and Mn(II) complexes exhibited higher potency as compared to the parent drug against gram-negative bacteria.

Abstract
The oxazolidinones are a promising new class of synthetic antibacterial agents. Here, we review recent efforts directed at the discovery of new antibacterial compounds of this class. New structures and structure-activity relationships (SAR) are discussed in the context of earlier work in the field. Key issues of potency, spectrum, selectivity, in vivo efficacy, and pharmacokinetic profile of the new analogs are addressed.
