Breast cancer (BC) is the most diagnosed cancer worldwide, mainly affecting the epithelial cells from the mammary glands. When it expresses the estrogen receptor (ER), the tumor is called luminal BC, which is eligible for endocrine therapy with hormone signaling blockade. Hormone therapy is essential for the survival of patients, but therapeutic resistance has been shown to be worrying, significantly compromising the prognosis. In this context, the need to explore new compounds emerges, especially compounds of plant origin, since they are biologically active and particularly promising. Natural products are being continuously screened for treating cancer due to their chemical diversity, reduced toxicity, lower side effects, and low price. This review summarizes natural compounds for the treatment of luminal BC, emphasizing the activities of these compounds in ER-positive cells. Moreover, their potential as an alternative to endocrine resistance is explored, opening new opportunities for the design of optimized therapies.
Introduction: The development of extended-spectrum-beta-lactamase (ESBLs) () has become a global threat to public health. An alternative strategy to alleviate this is identifying potential natural compounds to restore antibiotic activity against ESBLs . This study aimed to find a possible compound to restore ESBLs sensitivity to ceftiofur.
Betulin is a bioactive compound found in large quantities in birch bark and has a triterpene pentacyclic structure. Through the oxidation of betulin, betulinic acid is obtained, which is found in large quantities in nature. Betulin and betulinic acid have multiple pharmacological properties such as antiviral, anti-inflammatory, and anticancer properties.
Photosensitizers and pigments in raw meat such as porphyrins, riboflavin, and myoglobin after incorporation with light beam prompt the generation of singlet oxygen (O) from triplet oxygen (O) and cause oxidative rancidity of meat products. In this study, the results of photooxidation reactions of sheep erythrocyte (red blood cell) model as a model rich in hemoglobin and phospholipids bilayer, and oleic acid model were obtained by H NMR spectroscopy, TBARS assay, and iodometric titration. In both models, the rate of lipid photooxidation in the presence of hydroalcoholic extracts of Turmeric ( L.
Cardiovascular disease (CVD) poses a major risk to human health and exert a heavy burden on individuals, society, and healthcare systems. Therefore, it is critical to identify CVD's underlying mechanism(s) and target them using effective agents. Natural compounds have shown promise as antioxidants with cardioprotective functions against CVD injuries due to their antioxidative solid capacity and high safety profile.
Cystitis glandularis (CG), known as a pre-gradual lesion in the bladder, is the pathological changes in the vesical mucosa characterized by inflammatory invasion and chronic obstruction. Clinically, effective treatment against CG is prescribed only when using drug therapy. Fucoidan, the naturally extractive polysaccharide, is well-reported bioactive compound with anti-inflammatory and immunoregulatory properties.
