A Core-Linker-Polyamine (CLP) Strategy Enables Rapid Discovery of Antileishmanial Aminoalkylquinolinecarboxamides That Target Oxidative Stress Mechanism.

A Core-Linker-Polyamine (CLP) strategy has been exploited to develop new antileishmanial agents. It involves the linker-based assembly of alkyl-polyamine side chain as a potential pharmacophore motif with a privileged heterocyclic motif, 4-arylquinoline. A series of aminoalkyl 4-arylquinoline-2-carboxamides and their analogs were synthesized and tested against L.

Synthesis of N-substituted indole derivatives as potential antimicrobial and antileishmanial agents.

Leishmaniasis and microbial infections are two of the major contributors to global mortality and morbidity rates. Hence, development of novel, effective and safer antileishmanial and antimicrobial agents having reduced side effects are major priority for researchers. Two series of N-substituted indole derivatives i.

Pyridoxal kinase: A vitamin B6 salvage pathway enzyme from Leishmania donovani.

Pyridoxal kinase (PdxK, EC 2.7.1.

Functional analysis of an AMP forming acetyl CoA synthetase from Leishmania donovani by gene overexpression and targeted gene disruption approaches.

Leishmaniasis, a neglected tropical disease is endemic in 98 countries and >350 million people are at risk of getting the infection. The existing chemotherapy of Leishmaniasis is limited due to adverse effects, resistance to existing drugs and increasing cases of HIV-Leishmaniasis co-infection. Hence, there is a need to identify novel metabolic pathways for design of new chemical entities.

Exploring Leishmania donovani 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) as a potential drug target by biochemical, biophysical and inhibition studies.

3-Hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase (HMGR), an NADPH dependant enzyme catalyzes the synthesis of mevalonic acid from HMG-CoA required for isoprenoid biosynthesis. The HMGR gene from Leishmania donovani was cloned and expressed. Genome analysis of L.

Study of sugarcane pieces as yeast supports for ethanol production from sugarcane juice and molasses using newly isolated yeast from toddy sap.

A repeated batch fermentation system was used to produce ethanol using Saccharomyces cerevisiae strain (NCIM 3640) immobilized on sugarcane (Saccharum officinarum L.) pieces. For comparison free cells were also used to produce ethanol by repeated batch fermentation.
