Targeting GABA receptors with chalcone derivative compounds, what is the evidence?

INTRODUCTION: In medicinal chemistry, privileged structures have been frequently exploited as a successful template for drug discovery. Common simple scaffolds like chalcone are present in a wide range of naturally occurring chemicals. Chalcone exhibits extensive biological activity and has drawn attention in this context due to its function in the GABA receptor. Epilepsy and GABA receptors are related. It is a chronic neurological condition that affects globally. AREAS COVERED: Numerous neurological disorders, including anxiety and epilepsy, have been related to GABA, the brain's most prevalent inhibitory neurotransmitter. We go through the role of GABA receptors in anxiety and epilepsy in this review. The structure-activity relationship of chalcone and its derivatives on the GABA receptor is covered in our final section. EXPERT OPINION: GABA is a potential therapeutic target for issues associated with the nervous system. We talk about the potential effects of chalcone as a treatment for epilepsy and anxiety on the GABA receptor. Therefore, thorough research is necessary in this regard; the value of in silico tools in developing and enhancing GABA agonists is significant.

The economic burden of topical corticosteroid use in dermatophytosis: a cost-of-illness analysis of steroid-modified vs. steroid-naive dermatophytosis.

Dermatophytosis is one of the leading causes of visits to the dermatology department, especially in India, where the hot and humid climate favours fungal acquisition and perpetuation. Usual modalities of treatment include the use of either oral or topical antifungals or a combination of both, depending on the severity and extent of infection as well as the type of causative organism. But recently, steroid-modified dermatophytosis, an iatrogenically perpetuated dermatophytosis caused by the indiscriminate use of topical corticosteroids has emerged as a troublesome epidemic. We planned a cost-of-illness analysis of superficial dermatophytosis comparing the direct healthcare costs in steroid-naive and steroid-modified dermatophytosis. In our study, the average total cost of treatment for steroid-naive and steroid-modified dermatophytosis was found to be rupees (Rs) 2172.42 and Rs 3770.61 respectively, meaning that the cost for patients who used topical steroids is an additional 40% on average for treatment, when compared with the cost for patients who are steroid naive. The need for more consultations, investigations (relating to atypical presentation) and extended duration of treatment with higher-grade antifungals were found to contribute to the increased financial burden in steroid-modified dermatophytosis.

Pathophysiological basis in the management of myasthenia gravis: a mini review.

Myasthenia gravis is an autoimmune disorder characterized by the presence of autoantibodies against the acetylcholine receptor present in the post-synaptic membrane of the neuromuscular junction impairing the muscle contraction and causing the patient suffering from the disorder to develop a myriad of muscular defects ranging from drooping of eyelids, blurred or double vision, shortness of breath, difficulty in swallowing, as well as weakness of limbs and arms. Myasthenia gravis is known as the disease of old men and young women but in contrast to the global scenario, in India, myasthenia gravis was found to be predominant in males with the ratio of 2.70:1. Though the disorder has been studied for centuries, the true reason for disease and its pathophysiology still eludes us. But recent advancement in molecular biology and diagnostic tools has enabled us to identify many targets for pharmacotherapy as well as for early diagnosis. Thus, improving the patient's morbidity and quality of life. In this article, we are discussing the recent advancements made in diagnosis and therapy of the disease.

Mucus targeting as a plausible approach to improve lung function in COVID-19 patients.

COVID-19 (SARS-CoV-2) has emerged as one of the worst pandemics that have tormented the globe due to its highly contagious nature. Even if the disease manifests fever-like symptoms mostly, the disease may progress to the pulmonary-hyper inflammatory phase, with severe pneumonia, hypoxia and subsequent multiple organ infection. This subsequently creates a huge burden to the health care systems across the globe for an immediate arrangement of ventilator facilities, oxygen supply and advanced health care. We evaluated the pathological similarity of COVID-19 with other airway obstructive disorders such as COPD and asthma and found typical mucus hypersecretion and mucus plugging in COVID-19 subjects. From several bronchoscopy and clinical autopsy carried out in COVID-19 patients, the overexpression of mucin gene was evident which play a significant role in mucus hypersecretion and accumulation, leading to airway obstruction and further to respiratory distress. In the present work, we highlight the need for intense research inputs to elucidate the exact role the mucus plays in worsening COVID-19 symptoms. This will further help to find a proper approach to quantify the airway mucus plugging in each patient and to develop an appropriate therapy either to inhibit mucus secretion or to improve mucus clearance through well-designed clinical trials.
