β-Nicotinamide mononucleotide (β-NMN), a key precursor in the biosynthesis of nicotinamide adenine dinucleotide (NAD+) in mammals, has significant effects in replenishing NAD+ levels in the body, so it has obvious ameliorative effects on metabolic and age-related degenerative diseases. β-NMN is widely used in healthcare products, food, and cosmetics. It has considerable commercial worth and promising medic Read More

Melia azedarach L., a species of the mahogany family (Meliaceae), has long been used as a folk medicine for various diseases. Recent studies on this plant revealed that this plant contains many interesting bioactivities such as antioxidant, antimicrobial, antiviral, antifeedant, antidiabetic, antifungal, and cytotoxic activities. A diverse range of organic compounds has been isolated from this species, such as triterpenoids, lim Read More

Breast cancer was diagnosed in around 2.3 million women in 2020. Owing to the alarming rise in the incidence of breast cancer, newer small molecules with targeted therapy are the need of the hour. A plethora of small molecules has been approved by the USFDA in the past few years. Triazine is a six-membered aromatic nitrogen heterocyclic molecule that was investigated for its various types of biological activities spe Read More

Owing to the prevalent occurring in natural products and abundant bioactivities, the effective synthetic methods of fused bicyclic N,O-acetals skeletons are of great interest to chemists. This mini-review summarized the thus far synthetic progress of fused bicyclic N,O-acetals. These works were elaborated according to the different reaction types, including a) hetero-Diels-Alder cycloaddition of cyclic enamines with oxadiene Read More

New coumarin chalcones 3j-p were conveniently obtained in high yields via Claisen-Schmidt condensation reaction, when acetyl coumarin 1 reacted with 3-aryl-1-phenyl pyrazole-4-carbaldehydes 2j-p in boiling ethanol in the presence of triethyl amine as a catalyst. Also, two synthetic pathways were afforded for the synthesis of novel tetrazolo[1,5- a]pyrimidinyl-2H-chromen-2-ones 5a-p. The first pathway is a multistep process in Read More

Aril azides are popular reagents in the laboratory, but their explosive properties prevent their larger-scale application. The safety risk is even greater for N-heterocyclic azides, which are rarely studied. Flow chemistry can be an effective tool in the synthesis and utilization of dangerous and explosive chemicals. In small-diameter flow reactors, good heat and mass transfer prevent local hot spots and side reactions, and since Read More
