Synthesis and Biological Evaluation of Novel Multi-target-Directed Benzazepines Against Excitotoxicity.

Excitotoxicty, a key pathogenic event is characteristic of the onset and development of neurodegeneration. The glutamatergic neurotransmission mediated through different glutamate receptor subtypes plays a pivotal role in the onset of excitotoxicity. The role of NMDA receptor (NMDAR), a glutamate receptor subtype, has been well established in the excitotoxicity pathogenesis.

In the present study, a series of organic and alkali metal salts of biphenylacetic acid (BPA) have been prepared and evaluated in vitro for percutaneous drug delivery. The physicochemical properties of BPA salts were determined using solubility measurements, DSC, and IR. The DSC thermogram and FTIR spectra confirmed the salt formation with organic and alkali metal bases.

Neuroprotective Potential of Novel Multi-Targeted Isoalloxazine Derivatives in Rodent Models of Alzheimer's Disease Through Activation of Canonical Wnt/β-Catenin Signalling Pathway.

Previous reports suggest that Alzheimer's disease is protected by cholinesterase inhibitors. We synthesized some isoalloxazine derivatives and evaluated them using in vitro cholinesterase inhibition assay. Two of the compounds (7m and 7q) were figured out as potent cholinesterase inhibitors.

A comprehensive patents review on cannabinoid 1 receptor antagonists as antiobesity agents.

Introduction: Obesity is a rapidly expanding worldwide health problem. Various targets are investigated presently for the treatment of obesity, but there remains an unmet need for an effective drug therapy with acceptable efficacy levels and reduced side effects. Targeting peripherally located cannabinoid 1 (CB1) receptors is an attractive strategy as these receptors play a vital role in energy homeostasis.

This article describes discovery of a novel and new class of cholinesterase inhibitors as potential therapeutics for Alzheimer's disease. A series of novel isoalloxazine derivatives were synthesized and biologically evaluated for their potential inhibitory outcome for both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). These compounds exhibited high activity against both the enzymes AChE as well as BuChE.

Potential of Piperazinylalkylester Prodrugs of 6-Methoxy-2-Naphthylacetic Acid (6-MNA) for Percutaneous Drug Delivery.

Piperazinylalkyl ester prodrugs (4a-5d) of 6-methoxy-2-naphthylacetic acid (6-MNA) (1) were synthesized and evaluated in vitro for the purpose of percutaneous drug delivery. These ionizable prodrugs exhibited varying aqueous solubilities and lipophilicities depending on the pH of the medium. The prodrugs (4a-5c) showed higher aqueous solubility and similar lipophilicity at pH 5.

Neuroprotective Role of Novel Triazine Derivatives by Activating Wnt/β Catenin Signaling Pathway in Rodent Models of Alzheimer's Disease.

It has been reported in the literature that cholinesterase inhibitors provide protection in Alzheimer's disease (AD). Recent reports have implicated triazine derivatives as cholinesterase inhibitors. These findings led us to investigate anti-cholinestrase property of some novel triazine derivatives synthesized in this laboratory.

Synthesis and biological evaluation of some novel pyrido[1,2-a]pyrimidin-4-ones as antimalarial agents.

Novel pyrido[1,2-a]pyrimidin-4-ones have been synthesized and evaluated for their antimalarial activity by SYBR Green I assay against erythrocytic stages of chloroquine (CQ) sensitive Pf 3D7 strain. The antimalarial screening of 42 different compounds revealed that 3-Fluorobenzyl(4-oxo-4H-pyrido [1,2-a]pyrimidin-3-yl)carbamate (21, IC50 value 33 μM) and 4-Oxo-N-[4-(trifluoromethyl)benzyl]-4H-pyrido[1,2-a]pyrimidine-3-carboxamide (37, IC50 value 37 μM) showed moderate antimalarial activity. Cytotoxicity study was performed against mammalian cell line (Huh-7) by using the MTT assay for the moderately active compounds.

Prospective therapeutic agents for obesity: molecular modification approaches of centrally and peripherally acting selective cannabinoid 1 receptor antagonists.

Presently, obesity is one of the major health problems in the developed as well as developing countries due to lack of physical work and increasing sedentary life style. Endocannabinoid system (ECS) and especially cannabinoid 1 (CB1) receptor play a key role in energy homeostasis. Food intake and energy storage is enhanced due to the stimulation of ECS hence, inhibition of ECS by blocking CB1 receptors could be a promising approach in the treatment of obesity.

Enhanced skin permeation of 6-methoxy-2-naphthylacetic acid by salt formation.

The aim of this work was to prepare salts of 6-methoxy-2-naphthylacetic acid (6-MNA) to improve its physicochemical properties for percutaneous application. 6-MNA, an active metabolite of non-steroidal anti-inflammatory drug nabumetone has long half life and has the tendency to penetrate well into synovial fluid. The physicochemical properties of 6-MNA salts were investigated by solubility measurements, differential scanning calorimetry (DSC) and infrared (IR).

Completing the cycle: The use of audit to develop a mental health service in times of austerity.

Background: A published audit demonstrated that a pilot psychiatric clinic failed to capture predicted numbers of women with severe and enduring mental illness.

Methods: On the basis of recommendations from this audit, along with those from the Royal College of Psychiatrists and NICE guidelines, a more comprehensive psychiatric service was developed to meet this demand and therefore manage risk more effectively.

Results: Over the course of a year, the new service attracted a higher rate of referrals of pregnant women with severe and enduring mental illness.

Management of Hypertension-Journey from Single Drug Therapy to Multitargeted Ligand Therapy: A Clinical Overview.

Hypertension is recognized as one of the leading risk factors for human morbidity and mortality. It is a major risk factor for myocardial infarction, congestive heart failure, stroke, and endstage renal disease. The difficulty in controlling hypertension is related, at least in part, to the complex pathogenesis of hypertension.

Design and synthesis of 6,7-dimethoxyquinazoline analogs as multi-targeted ligands for α1- and AII-receptors antagonism.

Multiple-targeted ligands can have certain advantages for the management of hypertension which has multiple controls. Molecules with dual bioactivities are available in literature for treating metabolic disorders like diabetes, hypertension and hypercholesterolemia. After scrutinizing the SAR of prazosin-type α1-blockers and AII-antagonists it was planned to develop dual α1- and AII-antagonists.

Nitrogen containing privileged structures and their solid phase combinatorial synthesis.

The existence of preferred molecular scaffolds that possess inherent biological activity, called privileged structures, is now well recognized. Such privileged structures not only provide enhanced drug-like properties but also give new hits for developing leads. The synthesis of combinatorial libraries, especially with the insertion of privileged substructures into heterocyclic moieties containing nitrogen, provides for a greater probability of the discovery of novel lead compounds using chemical transformation.

Novel 2-aminobenzamides as potential orally active antithrombotic agents.

In an effort to develop potent antithrombotic agents, a series of novel 2-aminobenzamide derivatives were synthesized and screened for their in vivo antithrombotic activity. Among the 23 compounds tested, compound (8g) showed the most promising antithrombotic activity, which was comparable with clinically used aspirin or warfarin, but at variance with these standard drugs, 8g did not exhibit the increased bleeding time, suggesting its potential as a novel antithrombotic agent.

Novel methods and strategies in the discovery of TACE inhibitors.

Introduction: Tumor necrosis factor-α (TNF-α) is a key player in inflammation and joint damage in rheumatoid arthritis (RA). One treatment approach to exclude TNF-α from the biological system is by inhibiting tumor necrosis factor-alpha converting enzyme (TACE), the enzyme responsible for the production of its active form. To date, a number of TACE inhibitors have been reported in the literature from various strategies and methods.

Falcipain inhibitors as potential therapeutics for resistant strains of malaria: a patent review.
