Cummins, and Rajesh Khanna Running head: CRMP-2 modifies LCM’s actions on Na channels From the Departments of Pharmacology and Toxicology, Chemistry, Biochemistry and Molecular Biology and Center for Computational Biology, and(More)
The novel antiepileptic drug, (R)-N-benzyl 2-acetamido-3-methoxypropionamide ((R)-lacosamide, Vimpat(®) ((R)-1)), was recently approved in the US and Europe for adjuvant treatment of partial-onset seizures in adults. (R)-1 preferentially enhances slow inactivation of voltage-gated Na(+) currents, a pharmacological process relevant in the hyperexcitable(More)
The neuronal circuit remodels during development as well as in human neuropathologies such as epilepsy. Neurite outgrowth is an obligatory step in these events. We recently reported that alterations in the phosphorylation state of an axon specification/guidance protein, the collapsin response mediator protein 2 (CRMP2), play a major role in the(More)
The anti-epileptic drug (R)-lacosamide ((2R)-2-(acetylamino)-N-benzyl-3-methoxypropanamide (LCM)) modulates voltage-gated sodium channels (VGSCs) by preferentially interacting with slow inactivated sodium channels, but the observation that LCM binds to collapsin response mediator protein 2 (CRMP-2) suggests additional mechanisms of action for LCM. We(More)
Although the etiology of Parkinson's disease (PD) remains elusive, recent studies suggest that oxidative stress contributes to the cascade leading to dopaminergic (DAergic) neurodegeneration. The Nrf2 signaling is the main pathway responsible for cellular defense system against oxidative stress. Nrf2 is a transcription factor that regulates environmental(More)
Catechin derivatives with different alkyl chain length and aromatic ring substitutions at the 3-hydroxyl group were synthesized from epigallocatechin (EGC) and (+)-catechin (C) and their anti-influenza viral activity were evaluated in vitro and in ovo. Pronounced antiviral activity was observed for derivatives carrying moderate chain length (7-9 carbons) as(More)
By changing the structure or replacing the gallate group of (-)-ECG, 3-O-acyl and alkyl-(-)-epicatechin derivatives were synthesized to be screen as anticancer agents using the MTT assay in vitro against cancer cell lines (PC3, SKOV3, U373MG). 3-O-Acyl and alkyl-(-)-epicatechin derivatives (4-25) exhibited better anticancer activity than (-)-ECG and(More)
A series of 45 phenethylamine derivatives were synthesized and evaluated for their inhibitory activity against pig kidney aldose reductase (ALR2, EC Their IC(50) values ranged from 400 microM to 24 microM. The binding modes of compounds at the active site of ALR2 were examined using flexible docking. The results indicated that phenethylamine(More)
(R)-Lacosamide ((R)-2, (R)-N-benzyl 2-acetamido-3-methoxypropionamide) has recently gained regulatory approval for the treatment of partial-onset seizures in adults. Whole animal pharmacological studies have documented that (R)-2 function is unique. A robust strategy is advanced for the discovery of interacting proteins associated with function and toxicity(More)
The structure-activity relationship (SAR) for the N-benzyl group in the clinical antiepileptic agent (R)-lacosamide [(R)-N-benzyl 2-acetamido-3-methoxypropionamide, (R)-3] has been explored. Forty-three compounds were prepared and then evaluated at the National Institute of Neurological Disorders and Stroke Anticonvulsant Screening Program for seizure(More)
