Background: Larrea tridentata is a dominant shrub in the deserts of North America and is recognized for its various traditional uses. More than 50 traditional uses have been recorded. Regarding its chemical composition, the products of the mevalonate, shikimate, and malonate pathways are predominant. L. tridentata has nordihydroguaiaretic acid (NDGA), one of its most studied secondary metabolites that exhibited remarka Read More

Natural products are an important source of bioactive molecules. However, the development of biological applications based on these compounds is hindered by intrinsic problems in their solubility, volatility, degradation, and bioavailability. Nanocarriers as drug administration systems promise to overcome these limitations by providing controlled and directed delivery. This review aims to present 1) the most frequently used nan Read More

The natural product specialized metabolites produced by microbes and plants are the backbone of our current drugs. Ironically, we are in a golden age of understanding natural product biosynthesis, biochemistry, and engineering. These advances have the potential to usher in a new era of natural product exploration and development, taking full advantage of the unique and favorable properties of natural product compoun Read More

Lichens are a symbiotic association between a fungus (mycobiont) and a green algae/- cyanobacterium (photobiont). Lichens are a source of secondary metabolites, most of them being exclusively for these species, among which dibenzofurans are found. Dibenzofurans are a small group (over 35 different identified compounds), being usnic acid the most studied. In the last 10 years, there has been a growing interest in th Read More

Background: Cissus incisa is a Vitaceae with a pantropical distribution. In northern Mexico, its leaves have traditionally been used to treat skin infections, abscesses and tumors. Despite its medicinal uses, few studies have been reported. Objective: The objective of this study is to summarize the phytochemical and biological studies carried out so far on the leaves of C. incisa, since this part of the plant is the one frequently us Read More

Background and Objective: Osteoporosis is a worldwide healthcare challenge. Conventional medications for osteoporosis prevention are not clinically effective or associated with gastrointestinal tract adverse effects. The present study aimed to comparatively investigate the effects of technetium-99 conjugated with methylene diphosphonate (99Tc-MDP) and calcium carbonate and alendronate on the prevention and tre Read More
