Scientists are becoming alarmed by the rise in drug-resistant bacterial and fungal strains, which makes it more costly, time-consuming, and difficult to create new antimicrobials from unique chemical entities. Chemicals with pharmacological qualities, such as antibacterial and antifungal elements, can be found in plants. Alkaloids are a class of chemical compounds found in nature that mostly consist of basic nitrogen atoms. Biomedical science relies heavily on alkaloid compounds. Based on 241 papers published in peer-reviewed scientific publications within the last ten years (2014–2024), we examined 248 natural or synthesized monomeric alkaloids that have antifungal and antibacterial activity against Gram-positive and Gram-negative microorganisms. Based on their chemical structure, the chosen alkaloids were divided into four groups: polyamine alkaloids, alkaloids with nitrogen in the side chain, alkaloids with nitrogen heterocycles, and pseudoalkaloids. With MIC values of less than 1 µg/mL, compounds 91, 124, 125, 136–138, 163, 164, 191, 193, 195, 205 and 206 shown strong antibacterial activity. However, with MIC values of below 1 µg/mL, compounds 124, 125, 163, 164, 207, and 224 demonstrated strong antifungal activity. Given the rise in antibiotic resistance, these alkaloids are highly significant in regard to their potential to create novel antimicrobial drugs.

The most prevalent chronic neurodegenerative illness in the world is Alzheimer’s disease (AD). It results in mental symptoms including behavioral abnormalities and cognitive impairment, which have a substantial financial and psychological impact on the relatives of the patients. The review discusses various pathophysiological mechanisms contributing to AD, including amyloid beta, tau protein, inflammation, and other factors, while emphasizing the need for effective disease-modifying therapeutics that alter disease progression rather than merely alleviating symptoms. This review mainly covers medications that are now being studied in clinical trials or recently approved by the FDA that fall under the disease-modifying treatment (DMT) category, which alters the progression of the disease by targeting underlying biological mechanisms rather than merely alleviating symptoms. DMTs focus on improving patient outcomes by slowing cognitive decline, enhancing neuroprotection, and supporting neurogenesis. Additionally, the review covers amyloid-targeting therapies, tau-targeting therapies, neuroprotective therapies, and others. This evaluation specifically looked at studies on FDA-approved novel DMTs in Phase II or III development that were carried out between 2021 and 2024. A thorough review of the US government database identified clinical trials of biologics and small molecule drugs for 14 agents in Phase I, 34 in Phase II, and 11 in Phase III that might be completed by 2028.

This study examines the intricacies of Alzheimer’s disease (AD), its origins, and the potential advantages of various herbal extracts and natural compounds for enhancing memory and cognitive performance. Future studies into AD treatments are encouraged by the review’s demonstration of the effectiveness of phytoconstituents that were extracted from a number of plants. In addition to having many beneficial effects, such as improved cholinergic and cognitive function, herbal medicines are also much less harmful, more readily available, and easier to use than other treatments. They also pass without difficulty through the blood–brain barrier (BBB). This study focused on natural substances and their effects on AD by using academic databases to identify peer-reviewed studies published between 2015 and 2024. According to the literature review, 66 phytoconstituents that were isolated from 21 distinct plants have shown efficacy, which could be encouraging for future research on AD therapies. Since most clinical trials produce contradictory results, the study suggests that larger-scale studies with longer treatment durations are necessary to validate or refute the therapeutic efficacy of herbal AD treatments.

Background: Acute coronary syndrome (ACS) is the leading cause of death worldwide despite advances in treatment and prevention measures. This study aimed to explore ACS treatment strategies (ischemia-guided vs early invasive) and risk factors among patients diagnosed with ACS in a tertiary care hospital in Palestine and to evaluate related outcomes regarding future events and standard clinical guidelines. Methods: This retrospective cohort study reviewed patient data from a Palestinian medical hospital. The study included 255 patients ≥ 18 years who were hospitalized between January 2021 and December 2021 and diagnosed with ACS. The data were analyzed using the Statistical Package for Social Science (SPSS). Results: 71% of the participants were males. The mean age was 59.59± 11.56 years. Smoking, diabetes, and hypertension were the most common risk factors. Unstable angina (UA) was the most prevalent ACS type, accounting for 43.1% (110) of cases, whereas NSTEMI accounted for 39.2% (100) and STEMI accounted for 17.6% (45) of cases. An ischemic-guided strategy approach was used in 71% (181) of the patients. Upon discharge, the most prescribed medication classes were antiplatelets (97.6%), statins (87.1%), PPIs (72.5%), and antihypertensives (71.8%). Treatment strategies were selected according to the clinical guidelines for most ACS types. Conclusion: ACS management in Palestine continues to evolve to overcome barriers, decrease patient mortality, and decrease hospital stay. UA and NSTEMI were the most common ACS diagnoses at admission, and the ischemic strategy was the most common modality. The findings of this study call for an increased awareness of CVD risk factors, resource availability, and adherence to clinical guidelines to improve patient outcomes and community health.
