Aim: The present study was designed to synthesize novel Schiff bases and their metal complexes with promising antimicrobial and anti-angiogenic potential. Background: Currently, drug resistance has been seen in a diverse range of microbes, which is considered a major threat to widespread infectious diseases. Therefore, it is essential to investigate novel therapeutic molecules with broad-spectrum activities. Method: The novel Schiff base ligands were synthesized by using a condensation reaction of ethylenediamine with p-chloroacetanilide and p-bromoactanilide. Fe(III), Ni(II), Mn(II), and Co(II) metal complexes were prepared by refluxing the ligand with respective metal chloride salts in a 2:1 molar ratio. Results: Structures of the synthesized compounds were characterized by IR, 1H NMR, UV-VIS, and mass spectrometry. Anti-microbial activities of all the synthesized compounds were determined against bacterial strains (S. aureus and K. pneumoniae) and fungal strains (A. niger and Trichophytonrubrum) by using the well plate diffusion method. DNA photo-cleavage and anti-angiogenic properties were evaluated by gel electrophoresis and CAM assay, respectively. Molecular docking studies were performed to analyze the binding interactions of synthesized compounds with topoisomerase II alpha. Conclusion: The present preliminary efforts may be helpful to design novel drugs with therapeutic potential.

Quercetin is one of the most powerful bioactive dietary flavonoids. The in vivo biological study of quercetin is extremely difficult due to its very low solubility. However, diorganotin complexes of quercetin are more useful when contrasted with quercetin due to increased solubility. In the present study, quercetin, substituted biguanide synthesized in the form of Schiff base and its di-alkyl/aryl tin (IV) complexes were obtained by condensing Schiff base with respective di-alkyl/aryl tin (IV) dichloride. Advanced analytical techniques were used for structural elucidation. The results of biological screening against Gram-positive/Gram-negative bacteria and fungi showed that these diorganotin (IV) derivatives act as potent antimicrobial agents. The in silico investigation with dihydropteroate (DHPS) disclosed a large ligand–receptor interaction and revealed a strong relationship between the natural exercises and computational molecular docking results.

In India, microfinance is one of the most important innovations in anti-poverty policy in the last half-century. Microfinance has been accepted as a tool for growth. Significant divergence exists between local and external perspectives on use of money and other resources for gender. The general idea of the paper is to assess and evaluate the contribution of microfinance institutions for the empowerment of urban poor women. It explores impacts of microfinance on economic, social and overall empowerment perspectives of women; using different frameworks. The paper is based on primary data collected from 120 women through questionnaire along with secondary data to assess the impact of MFIs in relation to Non-Government Organizations (NGOs). Results found that most urban women in this association experienced increased income and educational level, therefore improved their economic status and social conditions after receiving the loans from NGOs.
