Organochlorinated pesticides OCs are highly toxic due to their persistence and severe ill effects on ecosystem. OCs were used extensively for agricultural as well as for health purposes like DDT, used for controlling malaria etc. OCs persistence and bioaccumulation create lot of health hazards including cancer, nervous system disorders, and tumor etc. Due to their recalcitrant nature there is a...

Organotin compounds have been found different application in industries, agricultures and pharmacological sciences via their various physical and biological specifications. One of the most important applications of these compounds, especially tributyltin TBT is in marine antifouling paints and coatings. Concern about the accumulation of tributyltin compounds on fish and shellfish and the advers...

A quantitative structure-property relationship (QSPR) study is suggested for the prediction of retention times of volatile organic compounds. Various kinds of molecular descriptors were calculated to represent the molecular structure of compounds. Modeling of retention times of these compounds as a function of the theoretically derived descriptors was established by multiple linear regression (...

The present study reports a microwave-assisted method for the synthesis of twelve novel tricyclic 1,4-dihydropyridine derivatives in which dimethyl-substituted cyclohexane and / or tetrahydrothiophene rings are fused to the DHP ring. The structures of the compounds were confirmed by spectral methods and elemental analysis. The potassium channel opening effects of the compounds were determined o...

Disinfectants play a major role in the control of animal diseases by decontaminating the farm environment. We evaluated the virucidal efficacy of nine commonly used disinfectants on a nonporous surface contaminated experimentally with avian metapneumovirus (aMPV), avian influenza virus, or Newcastle disease virus (NDV). Phenolic compounds and glutaraldehyde were found to be the most effective a...

Species of Candida, primarily C. albicans and with increasing prevalence, C. glabrata, are responsible for the majority of fungal bloodstream infections that cause morbidity, especially among immune compromised patients. While the development of new antifungal agents that target the essential enzyme, dihydrofolate reductase (DHFR), in both Candida species would be ideal, previous attempts have ...

Breast cancer is the primary cause of cancer death in women. Although current therapies have shown some promise against breast cancer, there is still no effective cure for the majority of patients in the advanced stages of breast cancer. Development of effective agents to slow, reduce, or reverse the incidence of breast cancer in high-risk women is necessary. Chemoprevention of breast cancer by...

A series of N-alkyl-3-(alkylamino)pyrazine-2-carboxamides and their N-alkyl-3-chloropyrazine-2-carboxamide precursors were prepared. All compounds were characterized by analytical methods and tested for antimicrobial and antiviral activity. The antimycobacterial MIC values against Mycobacterium tuberculosis H37Rv of the most effective compounds, 3-(hexylamino)-, 3-(heptylamino)- and 3-(octylami...

At the early stage of drug discovery, many thousands of chemical compounds can be synthesized and tested (assayed) for potency (activity) with High Throughput Screening (HTS). With ever increasing numbers of compounds to be tested (now often in the neighborhood of 500,000) it remains a challenge to find strategies via sequential design that reduce costs while locating classes of active compound...
