Tightly regulated cysteine CA proteases play a major role in maintaining the homeostasis within cells. Subsequently, when these proteases are dysregulated and mislocalized they disrupt healthy cell dynamics and contribute to many life-threatening pathologies such arteriosclerosis, osteoporosis and cancer. As such many pharmaceutical companies and research teams are highly interested in these proteases as targets. One emergent strategy is the spatiotemporal control of biological processes. In relation to this, a series of spatiotemporally controlled …

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 …
Development Of Ruthenium/Terpyridine Complexes For Water Oxidation, Dakshika Chandrashani Wanniarachchi
Development Of Ruthenium/Terpyridine Complexes For Water Oxidation, Dakshika Chandrashani Wanniarachchi
Wayne State University Dissertations
The work presented in the dissertation is focused on developing catalysts for water oxidation. In this regard, a series of unsysmmetrical ruthenium complexes of type [Ru(terpy-R)(phen-X)Cl]PF6 where terpy-R= 4'-(4-methylmercaptophenyl)-2,2':6'2"-terpyridine and phen-X=H (1), X= 5-nitro (2), X=5,6-dimethyl (3), and X= 3,4,7,8-tretramethyl (4) was synthesized as precursors for self-assembled monolayers. Water oxidation properties of these complexes were evaluated in the presence of (NH4)2[Ce(NO3)6] as the sacrificial oxidant by measuring catalytic turnover number (TON) after 24 h of reaction time and rate of dioxygen evolution in solution during early stages of catalysis. The results revealed that all complexes 1 - 4 are catalytic …
