Abstract
Diorganotin carboxylates have received much interest in past decades due to their rich structural chemistry and wide range of applications in various fields. This review study provides an in-depth analysis of carbon NMR data of dimethyltin complexes. The absorptions shown by the carbonyl carbon, methyl groups attached to tin and the other carbons present in the complexes were presented in this study. The effects of nature and the number of substituents attached are also described in this report.

Design, synthesis, structure information and biochemical activity of new floro substituted organotin(IV) carboxylates. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2015; 154:99-107.

Abstract
Four new triorganotin(IV) complexes with general formula R3SnL (R=C4H9, C6H5, and L=3-[(fluorophenylamido)]propenoic acid, 3-[(fluorophenylamido)]propanoic acid) were synthesized and characterized by elemental analyses, FT-IR, NMR ((1)H, (13)C and (119)Sn), mass spectrometry and single crystal X-ray structural analysis. The disappearance of the OH peak of the carboxylic acid in the FT-IR and NMR spectra of the compounds conform the formation of the compound and suggests that the complexation occurs via oxygen atoms of the carboxylate moiety. FT-IR date shows the bidentate nature of the carboxylate moiety of the ligand as the Δν value in all complexes is less than 250. Crystallographic data for compound 2 showed that tin has distorted tetrahedral geometry with 433.42° angle around the central tin atom. The compounds (1-4) bind to DNA, resulting hypochromism shifts in UV-visible spectroscopy suggesting an intercalative mode of interactions. The compound-DNA interaction results (UV-visible and Viscometery) encourage using the compounds against HCV. The compounds (1-4) were screened for anti-HCV activity using Huh7.5 cell (human hepatoma cell) by the Gaussia Luciferase Assay and found to be biologically active. Based on Gaussia Luciferase Assay, compound 3 (Tributylstannic [3-(2-fluorophenylamido)propionate]) was taken for quantitative analysis by "QRT-PCR" using the serum of HCV patients and was found to have substantial anti-HCV activity. This work, demonstrated that compound 3 may be used as a potential anti-HCV agent in the future.

Abstract
This article contains the synthesis of a novel carboxylic acid derivative, its transition metal complexes and evaluation of biological applications. Six carboxylate complexes of transition metals, Zn(II) and Hg(II), have been successfully synthesized and characterized by FT-IR and NMR (1H, 13C). The ligand, HL, (4-[(2,6-Diethylphenyl)amino]-4-oxobutanoic acid) was also characterized by single crystal X-ray analysis. The complexation occurs via oxygen atoms of the carboxylate moiety. FT-IR date show the bidentate nature of the carboxylate moiety of the ligand as the Δν value in all complexes is less than that of the free ligand. The ligand and its complexes were screened for antifungal and antileishmanial activities. The results showed that the ligand and its complexes are active with few exceptions. UV-visible spectroscopy and viscometry results reveal that the ligand and its complexes interact with the DNA via intercalative mode of interaction. A new and efficient strategy to identify the pharmacophores and anti-pharmacophores sites in carboxylate derivatives for the antibacterial/antifungal activity using Petra, Osiris and Molinspiration (POM) analyses was also carried out.

Abstract
The titled compound, 4-(5-chloro-2-hydroxyphenylamino)-4-oxobut-2-enoic acid was synthesized and characterized by various techniques like elemental analyses, FT-IR, NMR ((1)H, and (13)C) and single crystal X-ray structural analysis. The appearance of the OH peak of the carboxylic acid in the FT-IR and NMR spectra conform the formation of the compound. A good agreement was found between the calculated values of C, H, N and found values in elemental analysis that show the purity of the compound. Protons H2 and H3 are in cis conformation with each other as conformed both from (1)H NMR as well as from single crystal X-ray analysis. The molecular structure of the title compound, C₁₀H₁₀NO₃Cl, is stabilized by short intramolecular OH---O hydrogen bonds within the molecule. In the crystal structure, intermolecular NH---O hydrogen bonds link molecules into zigzag chains resulting in a dendrimer like structure. The title compound was screened for biological activities like interaction with DNA, cytotoxicity, antitumor and antioxidant activities. DNA interaction study reveals that the binding mode of interaction of the compound with SS-DNA is intercalative as it results in hypochromism along with significant red shift of 5 nm. It was also found to be effective antioxidant of 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and show almost comparable antioxidant activity to that of the standard and known antioxidant, ascorbic acid, at higher concentration. The antitumor activity data of the compound shows that it can be used as potent antitumor agent.

Abstract
Fourteen new organotin(IV) complexes with general formula R2SnL2 or R3SnL where R = CH3, C2H5, C4H9, C6H5, C6H11, CH2-C6H5, C(CH3)3, C8H17 and L = N-[(2-methoxyphenyl)]-4-oxo-4-[oxy]butanamide were synthesized and characterized by elemental analyses, FT-IR, NMR ((1)H, (13)C and (119)Sn), mass spectrometry and single crystal X-ray structural analysis. Crystallographic data for four triorganotin(IV) complexes (R3SnL, R = CH3, C2H5, C4H9, CH2-C6H5) showed the tin has approximate trigonal bipyramidal geometry with the R groups in the trigonal plane. The carboxylate groups of ligands L bridge adjacent tin atoms, resulting in polymeric chains. In case of the diorganotin(IV) derivatives a six-coordinate geometry at the tin atom is proposed from spectroscopic evidence. The Me-Sn-Me bond angle in complex 7 was determined from the (2)J[(119)Sn-(1)H] value as 166.3° that falls in the range of six-coordinate geometry. The ligand and its complexes (1-14) were screened for their antimicrobial, antitumor, cytotoxic and antileishmanial activities and found to be biologically active. The ligand and its complexes bind to DNA via intercalative interactions resulting in hypochromism and minor bathochromic shifts as confirmed by UV-visible spectroscopy. Based on in vitro studies such as the potato disc method, the synthesized compounds were found to possess significant antitumor activity. Also, from cytotoxicity and DNA interaction studies, these compounds can also be used for the prevention and treatment of cancer. Gel electrophoresis assay was used to investigate the damage to double stranded super coiled plasmid pBR322 DNA by the synthesized compounds and compounds 1 and 7 were found to cause the maximum damage. All the synthesized compounds exhibit strong antileishmanial activity that was even higher than that of Amphotericin B, with significant cytotoxicity. This study, therefore, demonstrated the potential use of these compounds as source of novel agents for the treatment of leishmaniasis.

Abstract
Three Schiff base compounds ofN'-substituted benzohydrazide and sulfonohydrazide derivatives: N'-(2-hydroxy-3-methoxybenzylidene)-4-tert-butyl- benzohydrazide (1), N'-(5-bromo-2-hydroxybenzylidene)-4-tert-butylbenzohydrazide (2) and N'-(2-hydroxy-3-methoxybenzylidene)-4-methylbenzenesulfonohydrazide (3) were synthesized and characterized by elemental analysis, FT-IR, (1)H, (13)C NMR spectroscopy and single crystal analysis. The title compounds have been screened for their biological activities including, antibacterial, antifungal, antioxidant, cytotoxic, enzymatic activities as well as interaction with SS-DNA which showed remarkable activities in each area of research. The DNA binding of the compounds 1-3 with SS-DNA has been carried out with absorption spectroscopy, which reveals the binding propensity towards SS-DNA via intercalation mode of interaction. The intercalative mode of interaction is also supported by viscometric results. The synthesized compounds were also found to be effective against alkaline phosphatase enzyme. They also show significant to good antimicrobial activity against six bacterial and five fungal strains. The MIC (minimum inhibitory concentration) for antibacterial activity ranges from 1.95-500 μg/mL. Compounds 1-3 show cytotoxic activity comparable to the control. At higher conc. (100 μg/L) compound 3 shows 100% activity means that it has killed all brine shrimps. They were also found to be effective antioxidant of 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and show almost comparable antioxidant activity to that of the standard and known antioxidant, ascorbic acid.
