CURRENT AREAS OF INTEREST
Written records of the use of natural products as medicinal agents date back thousands of years. The oldest records come from Mesopotamia and date from about 2600 BC, however, it was not until the early 1800’s that the active principles from plants were isolated. Natural products isolated from plants, animals and microorganisms have made an important impact on curing the dreadful diseases for example taxol, vinca alkaloids, podophyllotoxins camptothecin derivatives for cancer treatment; pencillins, streptomycins, tetracyclines as antibiotics; quinine and artemisinin for malaria treatment.
Our major research activities are identification of biologically active lead molecules through activity guided fraction and isolation work on the medicinal plants, marine organisms and microorganisms for metabolic diseases (hyperglycemia, dyslipidemia), parasitic diseases (leishmania and malaria), cancer, HIV etc., and chemical transformation of natural products of biological importance to improve their potency. We synthesize these biologically active lead molecules and their analogues in our laboratory. We have identified several lead molecules from the Indian medicinal plants for various disease areas as described below and further work is in progress to develop natural products based drugs.

Antihyperglycemic and Antidyslipidemic Agents
India leads the world with largest number of diabetic subjects earning the dubious distinction of being termed the “diabetes capital of the world”. According to the Diabetes Atlas 2006 published by the International Diabetes Federation, the number of people with diabetes in India currently around 40.9 million is expected to rise to 69.9 million by 2025 unless urgent preventive steps are taken. According to World Health Organization (WHO), Cardiac diseases have nearly doubled in India, an alarming fact. Latest data collected from WHO, suggest that by 2010 there would be close to 100 million cardiac patients in India.
Obesity, insulin resistance (Diabetes) and dyslipidemia are generally found as a part of a complex mixture of metabolic abnormalities collectively known as the metabolic syndrome. As a part of our natural products program we identified few lead molecules from Indian medicinal plants for metabolic disorder diseases for example Aegeline, an alkaloidal amide isolated from the leaves of Aegle marmelos (bael), exhibits the potent lipid lowering activity and mild antihyperglycemic activity; 4-hydroxyisoleucine an unusual amino acid from Trigonella foenum graecum (methi seeds) exhibits dual activity (antidyslipidemic and antihyperglycemic). terpenoid derivatives (α-amyrin and lupeol) exhibits antihyperglycemic activity. Modified furanoflavonoids (pseudosemiglabrin and semiglabrin) isolated from Indigofera tinctoria showed good lipid lowering activity.

Antileishmanial agents
Kala-azar (Leishmaniasis) has re-emerged from near eradication. The annual estimate for the incidence and prevalence of kala-azar cases worldwide is 0.5 million and 2.5 million, respectively. Of these, 90% of the confirmed cases occur in India, Nepal, Bangladesh and Sudan. In India, it is a serious problem in Bihar, West Bengal and eastern Uttar Pradesh The protozoan parasite Leishmania cause a broad spectrum of diseases ranging from cutaneous healing skin lesions caused by L. major to a fatal visceral form called kala azar caused by L. donovani.
We identified an orally active antileishmnaial agent i. e., Peganine from the seeds of Peganum harmala. It induces apoptosis- like cell death in L. donovani. The binding interactions between peganine and DNA topoisomerase I in molecular modeling studies (docking) and experimental studies suggested that the apoptosis like cell death appears to be due to L. donovani’s topoisomerase I inhibition. We also obtained few natural chromenodihydrochalcones, which exhibits antileishmanial activity in in-vitro studies. We synthesized several analogues of these chalcones and studied their in-vitro and in-vivo antileishmanial activity.

Anticancer Agents
Cancer
is a class of diseases in which a group of cells display uncontrolled growth, invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis, or spreading to other locations in the body via lymph
or blood. Based on the cancer registry data of Indian Cancer Society, it is estimated that there will be about 800,000 new cancers cases in India every year. At any given point there is likely to be 3 times this load that about 240,000 cases.
In continuation of our drug discovery program on anticancer agents we isolated 2-deacetoxytaxinine J (2-DAT-J) in reasonably good yield (0.1%) from the Indian T. baccata (ssp. wallichiana). It has effects on the Ca2+ induced microtubule depolymerization.  2-DAT-J is a powerful inhibitor of P-glycoprotein (P-gp) activity, acting as efficient reversing agent in multi-drug resistant (MDR) cancer cells.


Anti HIV Agents
According to National Family Health Survey-II figures, India had an estimated 2.5 million people (range 2 and 3.1 million) between the ages of 15 and 49 years living with HIV in 2006. The country’s adult HIV prevalence is halved as well, and is now estimated to be approximately 0.36%. HIV prevalence among adult women is 0.29%; for men it is 0.43%. This puts India behind South Africa and Nigeria in numbers living with HIV.
Recently we initiated research programme on the calanolide class of compounds, which are known for their HIV reverse transcriptase inhibiting activity. We isolated few coumarins from Calophyllum inophyllum to develop anti HIV and anti TB compounds.

           

We also isolate novel compounds from natural sources and identify their complex chemical structures using modern NMR tools. For example we isolated few novel limonoids from Xylocarpus molluccensis,a triterpene from Peganum harmala and bisuracil derivative from marine sea hare (Dolabella auricularia).

 
   
 

Hands on experience in identifying the bioactive compounds from marine microorganisms. DST, New Delhi awarded  BOYSCAST fellowship during 2007-2008 to visit University of California to learn advance technique on marine microorganisms. As part of the program six new anthraquinone-γ-pyrones, saliniquinones A–F (16), which  are related to metabolites of the pluramycin/altromycin class, were isolated from a fermentation broth of the marineactinomycete Salinispora arenicola (strain CNS-325). Their structures were determined by analysis of one- and two-dimensional NMR spectroscopic and high-resolution massspectrometric data. The relative and absolute configurations of compounds 16 were determined by analysis of NOESY NMR spectroscopic data and by comparison of circular dichroism and optical rotation data with model compounds found in the literature. Saliniquinone A (1) exhibited potent inhibition of the human colon adenocarcinoma cell line (HCT-116) with an IC50 of 9.9 × 10–9 M. In the context of the biosynthetic diversity of S. arenicola, compounds 16 represent secondary metabolites that appear to be strain specific and thus occur outside of the core group of compounds commonly observed from this species.
