Abstract: Cucurbita pepo is used as a vegetable in Pakistan and its seeds are also rich in tocopherol. Data showed the pivotal role of tocopherol in the treatment of Parkinson's disease (PD). The current study was designed to probe into the antiparkinson activity of methanolic extract of C. pepo (MECP) seeds in the haloperidol-induced Parkinson rat model. Behavioral studies showed improvement in motor functions. The increase in catalase, superoxide dismutase, glutathione levels whereas the decreases in the malondialdehyde and nitrite levels were noted in a dose-dependent manner. Acetylcholine-esterase (AchE) activity was increased. Molecular docking results revealed significant binding interaction of selected phytoconstituents within an active site of target protein AchE (PDB ID: 4EY7). Furthermore, α-synuclein was up regulated with down regulation of TNF-α and IL-1β in the qRT-PCR study. Subsequently, ADMET results on the basis of structure to activity predictions in terms of pharmacokinetics and toxicity estimations show that selected phytochemicals exhibited moderately acceptable properties. These properties add knowledge towards the structural features which could improve the bioavailability of selected phytochemicals before moving towards the initial phase of the drug development. Our integrated drug discovery scheme concluded that C. pepo seeds could ameliorate symptoms of PD and may prove a lead remedy for the treatment of PD.

Abstract: Diabetes mellitus (DM) and coronavirus disease 2019 (COVID-19) are public health issues worldwide, and their comorbidities trigger the progress to severe disease and even death in such patients. Globally, DM has affected an estimated 9.3% adults, and as of April 18, 2021, the World Health Organization (WHO) has confirmed 141,727,940 COVID-19 confirmed cases. The virus is spread via droplets, aerosols, and direct touch with others. Numerous predictive factors have been linked to COVID-19 severity, including impaired immune response and increased inflammatory response, among others. Angiotensin receptor blockers and angiotensin converting enzyme 2 have also been identified as playing a boosting role in both susceptibility and severity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Specifically, in DM patients, both their control and management during this pandemic is herculean as the restriction periods have markedly h ered the maintenance of means to control glycemia, hypertension, and neuroendocrine and kidney diseases. In addition, as a result of the underlyin cardio-metabolic and immunological disorders, DM patients are at a higher risk of developing the severe form of COVID-19 despite other comorbidities, such as hypertension, also potentially boosting the development of higher COVID-19 severity. However, even in non-DM patients, SARS-CoV-2 may also cause transient hyperglycemia through induction of insulin resistance and/or pancreatic β-cell injury. Therefore, a strict glucose monitoring of DM patients with COVID-19 is mandatory to prevent life-threatening complications.

Abstract: In this present study, rhinacanthins-rich extract (RRE) and rhinacanthin C (RC) the main bioactive constituent of Rhinacanthus nasutus was investigated for their protective effect against diabetic nephropathy (DN). Diabetes was induced by administering nicotinamide (100 mg/kg, i.p.)/streptozotocin (60 mg/kg, i.p.) and diabetic rats were orally administered with RRE and RC for 4 weeks. RRE and RC significantly reduced the kidney index, renal oxidative stress markers, and pro-inflammatory cytokines. Furthermore, RRE and RC increased renal levels of glutathione, superoxide dismutase, catalase, and attenuated diabetic induced renal damages. In conclusion, RRE and RC confer protective effect against DN through the inhibition of oxidative stress and inflammation and could be a potential medicinal or nutritional supplement for the prevention of DN. PRACTICAL APPLICATIONS: Rhinacanthus nasutus is a medicinal plant that is extensively used in Thai traditional medicine as an antibacterial, antifungal, antidiabetic, and anti-inflammatory agent. The plant is rich in naphthoquinones, which confer it with several excellent bioactivities. The rich extract of the leaves was prepared with three major bioactive components and the extract was evaluated for its renoprotective effect in diabetic rats. The results from this study provides valuable pharmacological information that supports the use of the plant, especially the rich extract in the prevention and treatment of diabetes and diabetic complications.
