The anti-proliferative activity of the somatostatin analog RC-160 is limited by its short serum half life. To circumvent this limitation, fatty acids of chain lengths ranging from 4 to 18 were individually conjugated to the N-terminal residue of RC-160. The lipophilized derivatives of RC-160 were synthesized, purified and characterized. The(More)
Epirubicin (EPI) is an anthracycline antineoplastic agent, commercially available for intravenous administration only and its oral ingestion continues to remain a challenge. Present investigation is aimed at the development of poly-lactic-co-glycolic acid (PLGA) nanoparticles (NPs) for oral bioavailability enhancement of epirubicin. Developed formulation(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 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)
Epirubicin (EPI) is a P-gp substrate antracycline analogue which elicits poor oral bioavailability. In the present work, EPI loaded poly-lactide-co-glycolic acid nanoparticles (PLGA-NPs) were prepared by double emulsion approach and superficially decorated with polyethylene glycol (EPI-PNPs) and mannosamine (EPI-MNPs). Average hydrodynamic particle size of(More)
Purpose. Acromegaly is a symptomatically disabling condition, resulting from a growth hormone (GH) secreting pituitary tumor. The somatostatin analog RC-160 is known to potently inhibit hypersecretion of GH, from pituitary adenomas. However, the therapeutic potential of RC-160, is limited by its short serum half life. To overcome this limitation, fatty(More)
We describe the synthesis and anticancer activities of octapeptide analogs of somatostatin incorporating α,α-dialkylated amino acids. The designed analogs of somatostatin are: d-Phe1-Cys2-Tyr3-d-Trp4-Orn5-Xxx6-Pen7-Thr8-NH2 where Xxx=α-Aminoisobutyric acid (Aib), Diethyl glycine (Deg), 1-Aminocyclopentane carboxylic acid (Ac5c), and,(More)
ETHNOPHARMACOLOGICAL RELEVANCE Eclipta alba is traditionally known to potentiate hair growth promotion. AIM OF THE STUDY The study was aimed to investigate the efficacy of methanol extract of Eclipta alba as hair growth promoter. MATERIALS AND METHODS Pigmented C57/BL6 mice, preselected for their telogen phase of hair growth were used. In these species,(More)
A new series of 2,3-diaryl-4/5-hydroxy-cyclopent-2-en-1-one analogues replacing the cis double bond of combretastatin A-4 (CA-4) by 4/5-hydroxy cyclopentenone moieties was designed and synthesized. The analogues displayed potent cytotoxic activity (IC50<1 microg/mL) against a panel of human cancer cell lines and endothelial cells. The most potent analogues(More)
