One of the notable aspects of 3-Methyl-1-phenyl-2-pyrazolin-5-one is its potent action in comparison to other NSAIDs. Clinical studies have demonstrated that it can provide rapid relief from pain and inflammation, making it a valuable option for patients suffering from acute flare-ups. However, despite its effectiveness, the use of PBZ has been surrounded by controversy due to its side effect profile. Prolonged use of this medication has been linked to serious adverse effects, such as gastrointestinal bleeding, cardiovascular complications, and hematological disorders. As a result, its prescription has been curtailed, particularly in certain populations, such as the elderly.

Penicillin, a pioneer among antibiotics, once had a production process that caused significant environmental pollution. In recent years, with the application of eco-friendly pharma intermediates, penicillin production has become cleaner and more efficient. For instance, using biocatalysis instead of chemical catalysis not only increases penicillin yield but also significantly reduces wastewater and gas emissions, achieving green production processes. Additionally, optimizing fermentation techniques has improved the biosynthesis efficiency of penicillin, reduced chemical synthesis steps, and lowered energy and resource consumption.
