Apoptosis is the energy dependent programmed cell death. Improper function of apoptosis could lead to diseases such as cancers, strokes, Alziemer’s disease. Caspases are the enzymes involved in the later stage of this process. Peptidyl and non-peptidyl caspase inhibitors have been synthesized recently. These non-peptidyl compound classes which consist of pyrrolidinyl-5-sulfo isatins have showed a greater potency against executioner caspases, caspase-3 and -7. According to literature and for further …

Determination of distribution levels of environmentally important compounds in various environmental compartments is a major procedure in many fields including environmental risk assessment, food and drug safety, and the perfumery industry. Models for direct estimation of environmental properties were developed using gas chromatography and liquid-liquid partitioning. The developed models were used to derive descriptor values for environmentally important organic compounds. The accuracy of the developed models and descriptor values were demonstrated by the application to the estimation of standard environmental properties and by comparison with experimental solute property values.

Quantitative structure property relationships were constructed for totally organic biphasic partition …
