SO2 is emerging as a possible endogenous signaling molecule in mammals. In addition, SO2 has also shown pharmacological effects, presenting SO2 as a promising potential therapeutic agent. The past decade has witnessed steady advances in the development of small molecule-based SO2 prodrugs/donors with varied release mechanisms. Herein, we summarize various strategies employed for SO2 prodrug design. The remaining challenges and issues will also be discussed.The quest to find novel strategies to tackle respiratory illnesses has led to the exploration of the potential therapeutic effects of carbon monoxide (CO) as an endogenous signaling molecule and a cytoprotective agent. Further, several studies have demonstrated the pharmacological efficacy of CO in animal models of respiratory disorders, such as acute lung injury and pulmonary hypertension. Because of the gaseous nature of CO and its affinity for multiple targets, its controlled delivery has been a challenge. Past studies have employed different delivery modalities, including CO gas, HO-1 inducers, and CO donors, sometimes leading to substantive variations in the resulting pharmacological effects for various reasons. Herein, this review summarizes and analyzes the differences among the profiles of various CO-delivery modalities in terms of their efficacy, dosing regimen, and pharmacokinetics in airways models. We believe that analysis of these issues will help in understanding the fundamental roles of CO in airways, and eventually, contribute to its development as a medicine for respiratory diseases.Bacterial infections which cause a wide range of host immune disorders leading to local and systemic tissue damage, are still one of the main causes of patient morbidity and mortality worldwide. Treatment of bacterial infections is challenging, which is mainly attributed to the rapidly evolving resistance mechanisms, creating an urgent demand to develop novel antibacterial agents. Hybridization is one of the most promising strategies in the development of novel antibacterial drugs with the potential to address drug resistance since different pharmacophores in the hybrid molecules could modulate multiple targets and exert synergistic effects. Selleck Cyclopamine Isatin, distributed widely in nature, can exert antibacterial properties through acting on diverse enzymes, proteins, and receptors. Accordingly, hybridization of isatin pharmacophores with other antibacterial pharmacophores in one molecule may provide novel antibacterial candidates with broad-spectrum activity against various pathogens, including drug-resistant forms. This review aims to outline the recent advances of natural and synthetic isatin hybrids with antibacterial potential and summarize the structure-activity relationship (SAR) to provide an insight for the rational design of more active candidates, covering articles published between January 2012 and June 2021.
The aim of this study was to investigate the differences in early (EOAD) and late (LOAD) onset of Alzheimer´s disease, as well as glucose uptake, regional cerebral blood flow (R1), amyloid depositions, and functional brain connectivity between normal young (YC) and Old Controls (OC).

The study included 22 YC (37 ± 5 y), 22 OC (73 ± 5.9 y), 18 patients with EOAD (63 ± 9.5 y), and 18 with LOAD (70.6 ± 7.1 y). Patients underwent FDG and PIB PET/CT. R1 images were obtained from the compartmental analysis of the dynamic PIB acquisitions. Images were analyzed by a voxel-wise and a VOI-based approach. Functional connectivity was studied from the R1 and glucose uptake images.

OC had a significant reduction of R1 and glucose uptake compared to YC, predominantly at the dorsolateral and mesial frontal cortex. EOAD and LOAD vs. OC showed a decreased R1 and glucose uptake at the posterior parietal cortex, precuneus, and posterior cingulum. EOAD vs. LOAD showed a reduction in glucose uptake and R1 at the occipital anand may have an impact on patient diagnostic evaluation.In the next few years, the prevalence of diabetes mellitus (DM) is projected to dramatically increase globally, but most of the cases will occur in low-to-middle-income countries. Some of the major risk factors for diabetes accelerate the development of dementia in African-Americans, thus leading to a higher prevalence of dementia than Caucasians. Sub-Saharan Africa women have a disproportionately two-to-eight fold increased prevalence of dementia. In the eye of this storm, Nigeria holds the highest number of diabetics on the African continent, and its prevalence is rising in parallel to obesity, hypertension, and the population's aging. The socio-economic impact of the rising prevalence of DM and dementia will be huge and unsustainable for the healthcare system in Nigeria, as has been recognized in developed economies. Here, we analyze the current situation of women's health in Nigeria and explore future perspectives and directions. The complex interplay of factors involved in diabetes and dementia in Nigerian women include key biological agents (metabolic syndrome, vascular damage, inflammation, oxidative stress, insulin resistance), nutritional habits, lifestyle, and anemia, that worsen with comorbidities. In addition, restricted resources, lack of visibility, and poor management result in a painful chain that increases the risk and burden of disease in Nigerian women from youth to elderly ages. Heath policies to increase the ra- tio of mental health professionals per number of patients, mostly in rural areas, foment of proactive primary care centers, and interventions targeting adolescents and adult women and other specific mothers-children pairs are strongly required for a sustainable development goal.Diabetes mellitus (DM) is a type of chronic metabolic disease that has affected millions of people worldwide and is known with a defect in the amount of insulin secretion, insulin functions, or both. This deficiency leads to an increase in the amounts of glucose, which could be accompanied by long-term damages to other organs such as eyes, kidneys, heart, and nervous system. Thus, introducing an appropriate approach for diagnosis and treatment of different types of DM is the aim of several researches. By the emergence of nanotechnology and its application in medicine, new approaches were presented for these purposes. The object of this review article is to introduce different types of polymeric nanoparticles (PNPs), as one of the most important classes of nanoparticles, for diabetic management. To achieve this goal, at first, some of the conventional therapeutic and diagnostic methods of DM will be reviewed. Then, different types of PNPs, in two forms of natural and synthetic polymers with different properties, as a new method for DM treatment and diagnosis will be introduced. In the next section, the transport mechanisms of these types of nano-carriers across the epithelium, via paracellular and transcellular pathways will be explained. Finally, the clinical use of PNPs in the treatment and diagnosis of DM will be summarized. Based on the results of this literature review, PNPs could be considered one of the most promising methods for DM management.The hydroxycinnamic acid scaffold is extremely versatile with various biological activities. This review will highlight the progress of the biological activities of hydroxycinnamic acids and their related synthetic analogs, including recently reported anti-cancer, anti-inflammatory, and antioxidant activities.The beneficial effect of plants in treating diabetes is not only well-known in traditional medicine but also confirmed in numerous scientific studies. The basic platform for testing the potential antidiabetic activity of traditionally known plants and their bioactive compounds is a set of in vitro, in vivo experiments, clinical trials and molecular docking studies. Basic assays usually measure enzyme inhibitory activity (α-amylase and α-glucosidase) and other aspects related to diabetes mellitus disease. Recently, the use of plant-derived compounds has proven useful in treating diabetes and reducing complications resulting from high blood sugar levels. The main goal is to establish an action mechanism of plant extracts or active compounds to find new antidiabetic drugs with less toxicological properties. This work aims to collect data and discuss the newest results in the area of plant extracts, compounds and antidiabetic effects using in vitro, in vivo and in silico models. The data covered in this review include plant extracts, polyphenols, terpenoids, saponins, phytosterols, and other bioactive compounds, with some of the investigated plants being less known. Isolation of new compounds might be a plentiful source for treatment and prevention of diabetes mellitus. Clinical trials with adequate monitoring give the best results of plants' product efficacy and safety. Many studies give us the confirmation for importance of patent and use medicinal herbs in the treatment of diabetes.
Coumarin is an oxygen-containing compound in medicinal chemistry. Coumarin plays an important role in both natural systems like plants and also in synthetic medicinal applications as drug molecules. Many structurally different coumarin compounds were found to show a big range of similarity with the vital molecular targets for their pharmacological action and small modifications in their structures resulted insignificant changes in their biological activities.

This review gives detailed information about the studies of the recent advances in various pharmacological aspects of coumarins.

Various oxygen-containing heterocyclic compounds represented remarkable biological significances. The fused aromatic oxygen-heterocyclic nucleus is able to change its electron density; thus changing the chemical, physical and biological properties respectively due to its multiple binding modes with the receptors, which play crucial role in pharmacological screening of drugs. A number of heterocyclic compounds have been sycent activities against COVID -19. Natural compounds act as a rich resource for novel drug development against various SARS-CoV-2 viral strains including viruses like herpes simplex virus, influenza virus, human immunodeficiency virus, hepatitis B and C viruses, middle east respiratory syndrome and severe acute respiratory syndrome.The presence of hypertension among the population with human immunodeficiency virus (HIV) has become a new threat to the health and well-being of people living with this disease, in particular, among those who received antiretroviral therapy. The estimated prevalence of high blood pressure in HIV-infected patients is significantly higher than the rate observed in HIV-uninfected subjects. The approach to the HIV-positive patient requires the assessment of individual cardiovascular risk and its consideration when designing the individualized target. On the other hand, the numerous pharmacological interactions of antiretroviral (ARV) drugs are essential elements to take into account. Serum levels of any kind of antihypertensive drugs may be influenced by the coadministration of protease inhibitors, non-nucleoside reverse transcriptase inhibitor, or other antiretroviral. Similarly, plasma concentrations of antiretroviral drugs can be increased by the concomitant use of calcium channel blockers or diuretics. In this regard, the treatment of high blood pressure in HIV patients should be preferentially based on ACE inhibitors or thiazide/thiazide-like diuretics or their combination.
