The concept of molecular hybridization led us to discover a novel series of coumarin-dihydropyridine hybrids that have potent osteoblastic bone formation in vitro and that prevent ovariectomy-induced bone loss in vivo. In this context, among all the compounds screened for alkaline phosphatase activity, four compounds 10, 14, 18, and 22 showed significant(More)
A series of synthesized novel biscoumarin-chalcone hybrids were evaluated for their anti-inflammatory and antioxidant activity. The tested compounds significantly inhibit the carrageenin induced paw oedema in albino rats and also exhibit important scavenging activities. These compounds thus constitute an interesting template for the design of new(More)
The synthesis of a series of benzocoumarin keto-enamine schiff bases is reported. The novel compounds were evaluated for their antihyperlipidemic activity in the hyperlipidemic hamster model. The compound 11 at a dose of 10 mg/kg body weight significantly lowered the plasma triglyceride levels (TG) by 70%, total cholesterol (TC) by 47%, accompanied by an(More)
Here we report the synthesis of novel chalcone-thiazole compounds and their antifilarial activity. The antifilarial properties of these hybrids were assessed against microfilariae as well as adult worms of Brugia malayi. Among all the synthesized compounds, only two compounds, namely 4g and 4n were identified to be promising in vitro. These active compounds(More)
With increasing faults and attacks on the Internet infrastructure, there is an urgent need to develop techniques to analyze network and service vulnerability under organized fault attacks. Network vulnerability refers to the impact of attacks and faults on network and system behaviors. An accurate vulnerability analysis requires a deep understanding of(More)
In the search for effective multifunctional agents for the treatment of Alzheimer's disease (AD), a series of novel hybrids incorporating benzofuran and chalcone fragments were designed and synthesized. These hybrids were screened by using a transgenic Caenorhabditis elegans model that expresses the human β-amyloid (Aβ) peptide. Among the hybrids(More)
A series of novel keto-enamine chalcone-chloroquine based hybrids were synthesized following new methodology developed in our laboratory. The synthesized compounds were screened against chloroquine sensitive strain (3D7) of Plasmodium falciparum in an in vitro model. Some of the compounds were showing comparable antimalarial activity at par with(More)
A series of multifunctional directed 3-arylcoumarin-tetracyclic tacrine derivatives was designed and synthesized for the treatment of Parkinson's disease (PD). A number of derivatives (18, 19, 20, 21, and 24) demonstrated significant reduction of aggregation of "human" alpha-synuclein (α-synuclein) protein, expressing on transgenic Caenorhabditis elegans(More)
Anti-osteoporotic effects of the newly synthesized coumarin-pyridine hybrids were evaluated in primary cultures of rat calvarial osteoblasts in vitro. Compounds 6a, i, j and k were potent in stimulating osteoblast differentiation and mineralization as assessed by the alkaline phosphatase production and alizarin red-S staining assay, respectively.
