Dr Manisha Tiwari works focuses on the treatment of CNS and lifestyle disorders. The CNS disorders that we are working on include Alzheimer’s disease and epilepsy. Lifestyle disorders that we are researching include hyperlipidemia and cancer. Our laboratory works on the synthesis of small organic molecules for the treatment of these disorders. In the last 10 years we have synthesis several therapeutic agents for the treatment of Alzheimer’s Disease. One of the essential pharmacophores in our studies is aryl piperazine. We have prepared aryl piperazine derivatives, some of which have shown excellent activity against acetylcholinesterase and Abeta aggregation. In silico analysis of these derivatives including molecular docking studies and Molecular dynamics simulation studies have been carried out with A beta, which show strong interaction of these derivatives with the Abeta protein aggregates.

We have also prepared heterocyclic compounds for the treatment of cancer which have shown admirable activity in vivo
