The TWIK-related K(+) channel, TREK-1, has recently emerged as an attractive therapeutic target for the development of a novel class of analgesic drugs. It has been reported that TREK-1 -/- mice were more sensitive than wild-type mice to painful stimuli, suggesting that activation of TREK-1 could result in pain inhibition. Here we report the synthesis of a(More)
The histone deacetylase enzyme has increasingly become an attractive target for developing novel anticancer drugs. Hydroxamates are a new class of anticancer agents reported to act by selective inhibition of the histone deacetylase (HDAC) enzyme. Comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) were(More)
Cyclooxygenase-2 (COX-2) inhibitors are widely used for the treatment of pain and inflammatory disorders such as rheumatoid arthritis and osteoarthritis. A series of novel 2-(4-methylsulfonylphenyl)pyrimidine derivatives has been reported as COX-2 inhibitors. In order to understand the structural requirement of these COX-2 inhibitors, a ligand-based(More)
Histone deacetylases (HDACs) play a critical role in gene transcription and are implicated in cancer therapy and other diseases. Inhibitors of HDACs induce cell differentiation and suppress cell proliferation in the tumor cells. Although many such inhibitors have been designed and synthesized, but selective inhibitors for HDAC isoforms are lacking. Various(More)
We have designed and synthesized both the quinoline and naphthalene based molecules influenced by the unique structural make-up of mefloquine and TMC207, respectively. These compounds were evaluated for their anti-mycobacterial activity against drug sensitive Mycobacterium tuberculosis H37Rv in vitro at single-dose concentration (6.25 microg/mL). The(More)
We designed bidentate ligands to target PDZ domains through two binding sites: site S0, delimited by the GLGF loop, and site S1, a zone situated around loop β(B)/β(C). A molecular docking study allowed us to design a generic S0 binder, to which was attached a variable size linker, itself linked to an amino acid aimed to interact with the S1 site of PDZ(More)
We synthesized small organic molecules designed as PDZ ligands. These indole-based compounds were evaluated for their interaction with the PDZ1 domain of the post-synaptic density 95 (PSD-95) protein. Three molecules were found to interact with the targeted PDZ protein by NMR. One of them showed chemical shift perturbations closely related to the natural(More)
Disrupting the interaction between the PDZ protein, PSD-95, and its target ligands (such as the glutamate NMDA receptor or the serotonin 5-HT2A receptor) was found to reduce hyperalgesia in various models of neuropathic pain. Here, we set out to identify lead molecules which would interact with PSD-95, and hence, would potentially display analgesic(More)
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for the treatment of pain, fever and inflammatory diseases such as rheumatoid arthritis and osteoarthritis. A series of direct analogues of flurbriprofen [4'-methylbiphenyl-2-(substituted phenyl) carboxamide derivatives] have been reported as novel anti-inflammatory agent. In order to gain(More)
Various direct analogues of flurbriprofen [ 4'-methylbiphenyl-2-(substituted phenyl) carboxamide derivatives ] were synthesized and evaluated for anti-inflammatory activity by carrageenan induced rat paw edema model. Compounds 3g, 3h and 3i were found significantly active. Substituents –SO 2 NH 2 ,-F and-Cl exhibited significant anti-inflammatory activity.(More)
