An attempt was made to synthesize a series of non-cytotoxic low molecular weight compounds of varying substitutions and functionalities having pharmacophore activity like carbonyl compounds, carboxylicacid and bioisosteres like tetrazole and phenyl acrylic acid. The in vitro assay of these analogues for the inhibition of complement activity revealed significant inhibitory activity for varying substituents
A comparative study between heterogeneous stannous chloride loaded silica nanoparticles and a homogeneous stannous chloride catalyst in the synthesis of 5-substituted 1H-tetrazole
Heterogeneous SnCl2–nano-SiO2 efficiently catalyzed 5-substituted 1H-tetrazole synthesis with excellent yield. The catalyst was characterized by using FT-IR, TGA, TEM, and EDX. It is widely applicable on aliphatic, aromatic, heteroaromatic and sterically hindered nitriles with five time recyclability. Being simple and an economically viable approach for the synthesis of SnCl2–nano-SiO2 are additional
An effective one-pot, convenient gold catalyzed synthesis of 5-substituted 1H-tetrazoles has been discussed.

and Dimethyl sulfoxide to receptor 4 causes a change in colour of the solution from colourless to yellow. The stoichiometry for host:anion is 1:1. Furthermore, receptor 4 was used as an ion carrier in ion-selective membrane electrodes. Selectivity of this membrane was studied towards various anions in water solution. Binding behaviour of receptor 4 towards several anions (Cl− , F− , Br− , I− ) has

2′-MeC6H4, 2′-ClC6H4, or 2′,6′-Cl2C6H3), the rings are twisted out of the planar configuration and interannular conjugation is inhibited. In each case the tetrazole 1-NH tautomêr is strongly predominant. When the rings are coplanar, as in para-substituted-5-phenyltetrazoles, the electron-withdrawing effect of the para-substituents changes the tautomerism significantly back towards the 2-NH form. Methylation
