Summary: According to the WHO's data, the global cancer burden reached 18.1 million new cases in 2018, resulting in 9.6 million deaths. Pharmaceutical spending accounts for around 19% of the annual R&D cost to discover new anticancer drugs. However, drug resistance and side effects remain major issues. This review compiles and discusses analytical and bioanalytical methods for anticancer drugs, covering cytotoxic drugs and targeted-based drugs. The accuracy and precision of UV-HPLC, LC-MS, and fluorometry HPLC are examined, along with advanced methods such as Au/Pd@rGO@p(L-Cys) and endophytic fungi for drug production. This review aims to support researchers in overcoming the challenges in drug development.

Summary: Parkinson's disease is a neurodegenerative disorder characterized by symptoms such as slow movement, tremors, and stiffness, caused by the loss of dopaminergic neurons in the brain's substantia nigra. The disease is associated with a decrease in dopamine concentration in the brain and can be influenced by genetic and environmental factors. The irregular expression of the MAO-B enzyme, which causes the oxidative deamination of biogenic amines like dopamine, is implicated in Parkinson's disease. Current MAO-B inhibitors have adverse effects, and the development of new inhibitors with minimal side effects is urgently needed. Recent studies have identified potential lead compounds for the development of potent MAO-B inhibitors.

Summary: Piperazine derivatives have been synthesized and tested for their MAO inhibitory activity. Compound 5f and 5g showed the strongest potential as MAO-A inhibitors with IC50 values of 0.96 and 0.81 mu M, respectively. These compounds exhibited reversible inhibition of MAO-A without cytotoxicity and displayed good antioxidant activity. In vivo studies demonstrated their antidepressant-like activity. Molecular docking and dynamic studies confirmed the stable complex formation between these compounds and the MAO-A enzyme. These findings suggest that the piperazine clubbed oxadiazole structural framework is a promising target for developing new antidepressant molecules.
