In the title compound, C(14)H(17)NO(5)S, the thia-zine ring adopts a half-chair conformation. The mol-ecule exhibits an intra-molecular O-H⋯O hydrogen bond, which forms a six-membered S(6) ring motif. The planes of the benzene and thia-zine rings are inclined at a dihedral angle of 15.30 (12)°.

The synthesis, in vitro antimicrobial and cytotoxic activities of some novel hexahydroquinolines supported with various pharmacophores are described. The results revealed that 18 compounds displayed pronounced activity against Staphylococcus aureus and Escherichia coli bacteria beside a moderate antifungal activity. Compound 25 is the most active candidate with equipotency to ampicillin against S. aureus, E. coli and Pseudomonas aeruginosa, together with an obvious antifungal activity. Additionally, 12 compounds showed remarkable cytotoxic efficiency against human colon carcinoma HT29, hepatocellular carcinoma Hep-G2 and Caucasian breast adenocarcinoma MCF7 cell lines. Among these, the analogs 22 and 25 proved to be the most active cytotoxic members. Collectively, the results would suggest that compounds 22 and 25 could be considered as possible dual antimicrobial-anticancer agents.

Gold Nanoparticles - Reaching New Heights contains recent research on the preparation, characterization, fabrication, and potential of optical and biological applications of gold nanoparticles (AuNPs). It is promising novel research that has received a lot of interest over the last few decades. It covers advanced topics on optical, physical, medicinal, and biological applications of AuNPs. Development of green nanotechnology is generating the interest of researchers towards the synthesis of eco-friendly, safe, non-toxic applications, which can be used for manufacture at a large scale. These are simple, cost-effective, stable, enduring, and reproducible aqueous room temperature synthesis applications to obtain the self-assembly of AuNPs. This potentially unique work offers various approaches to R&D with AuNP materials in aqueous or non-aqueous phases through fully modified or unmodified states as hybrids. Nanotechnology and nanoscience can regulate substances at the nanoscale, and nanodimension substances of a few nanometers allow us to control the novel practical applications of AuNPs. This book presents an overview of current AuNP fundamental and substantial applications and research worldwide, which investigates the techniques of AuNP preparation, various types of characterization, and possible applications related to AuNP research. It is an important book for research organizations, government research centers, academic libraries, and R&D groups interested in recent research and development of AuNPs.
We report results from investigations of the nonlinear refractive index and nonlinear absorption coefficient of (2E)-3-[4-(Dimethylamino)phenyl]-1-(2,5-dimethylthiophen-3-yl)prop-2-en-1-one and (2E)-3-(3,4-Dimethoxyphenyl)-1-(2,5-dimethylthiophen-3-yl) prop-2-en-1-one using Z-scan technique with a continuous wave (cw) laser at wavelengths 488 nm and 514 nm. The nonlinear refractive index and nonlinear absorption coefficient of both samples were evaluated. The origin of the nonlinear effects was discussed. Optical limiting based on light induced nonlinear refractive index variation is demonstrated. The limiting thresholds were estimated for both samples. The results suggested that these materials offer promise as candidates for optical limiting and optical devices in the low power regime.
The imino–carbon double bond in the title Schiff base, C26H24N4O, has an E configuration. The 13-membered carbazolyl fused-ring (r.m.s. deviation = 0.056 Å) is nearly coplanar with five-membered pyrazole ring (r.m.s. deviation = 0.036 Å) [dihedral angle between the two systems = 10.4 (1)°]; the phenyl substituent is twisted by 51.1 (1)° with respect to the five-membered ring.
In the title compound, C(10)H(13)NO(3)S, prepared in a one-pot reaction, the mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The packing is consolidated by further N-H⋯O links. The H atoms of two of the methyl groups are disordered over two sets of sites with equal occupancies.
The asymmetric unit of the title compound, C(17)H(13)N(3), contains two independent mol-ecules, which are non-planar as they are buckled owing to the ethyl-ene portion. The dihedral angle between the benzene rings is 26.4 (1)° in one mol-ecule and 32.9 (1)° in the other. In the crystal, the mol-ecules are disposed about a false inversion center, and are linked by two N-H⋯N hydrogen bonds, generating a dimer. The dimers are linked by further N-H⋯N hydrogen bonds, resulting in a chain that runs along the longest axis of the ortho-rhom-bic unit cell.
