Cancer is one of the leading causes of death in the world. American Cancer Society reported 12 million new cases of malignancy diagnosed worldwide in 2007, with 7.6 million people dying from the disease. Plant-derived molecules have played an important role in cancer chemotherapy. Many cytotoxic plant-derived molecules such as vinblastine, vincristine,(More)
Terminalia arjuna has been marked as a potential cardioprotective agent since vedic period. The present study was aimed to investigate the effects of butanolic fraction of Terminalia arjuna bark (TA-05) on Doxorubicin (Dox)-induced cardiotoxicity. Male wistar rats were used as in vivo model for the study. TA-05 was administered orally to Wistar rats at(More)
A series of 3-O-acyl, 3-hydrazine, 2-bromo, and 20,29-dibromo betulinic acid derivatives (1-27) have been synthesized and screened for in vitro cytotoxic activity on human cancer cell lines MOLT-4, JurkatE6.1, CEM.CM3, BRISTOL8, U937, DU145, PA-1, A549, and L132. A number of compounds have shown ED(50)<1 microg/mL against the cancer cell lines tested and(More)
In vitro and in vivo pharmacological screening of Betulinic acid (BA) and five dihydro-BA derivatives modified at C-3 position [4-nitrobenzyl-oximino (1), 2-4-difluoro-benzoyloxy (2), 2-4-difluoro-benzylidene-amino (3), benzoyl-hydrazono (4), and 4-fluorophenyl-hydrazono (5)], having potent in vitro anti-cancer activity was carried out using ADME, animal PK(More)
A novel peptide combination consisting of four synthetic neuropeptide analogs of Vasoactive Intestinal Peptide (VIP), Bombesin, Substance P and Somatostatin has been found to have potent anticancer activity in vitro and in vivo. The receptors of these four neuropeptides are known to be over expressed in various cancers. We have found the presence of native(More)
A new series of betulinic acid derivatives have been synthesized by introducing heterocyclic ring between C-2 and C-3 positions of betulinic acid. Further modifications were also carried out by reduction of C-20(29) unsaturated bond and substitution of C-28 carboxyl group by ester and amide linkage to enhance the selectivity. Compound 11 resulted in IC(50)(More)
In the present review, the discovery and development of quinazoline as tyrosine kinase inhibitors has been described. The synthesis of most potent quinazoline inhibitors of EGFR, VEGFR and PDGRF has been discussed. Structure activity relationship for quinazoline as tyrosine kinase inhibitors has been established. It was found that C-4, C-6 and C-7 positions(More)
The degradation of docetaxel drug substance and its injection formulation has been investigated. The majority of impurities were observed in a base degradation study and all five degradation products were characterized. These impurities were isolated, enriched and were subjected to mass and NMR spectral studies. Based on the spectral data, these were(More)
Betulinic acid, a pentacyclic triterpene, is widely distributed throughout the tropics. It possesses several biological properties such as anticancer, anti-inflammatory, antiviral, antiseptic, antimalarial, spermicidal, antimicrobial, antileshmanial, antihelmentic and antifeedent activities. However, betulinic acid was highly regarded for its anticancer and(More)
Betulinic acid (1) significantly caused cytotoxicity to endothelial cell line ECV304 (IC(50) 1.26+/-0.44 microg/mL) in a 5-day MTT assay. Novel and more potent derivatives of betulinic acid (2, 4, 6-8) have been synthesized with IC(50) less than 0.4 microg/mL. The endothelial cell specificity against human tumor cell lines DU145, L132, A549, and PA-1 were(More)
