The synthesis of Active Pharmaceutical Ingredients (APIs) in aqueous media has emerged as a transformative approach in modern process chemistry 🌍. Traditionally, API manufacturing relies heavily on organic solvents, many of which are volatile, toxic, and environmentally hazardous. Replacing these solvents with water—a non-toxic, non-flammable, and abundantly available medium 💧—offers a sustainable alternative aligned with green chemistry principles. In academic research, water-based reactions are gaining attention due to improved atom economy, safer reaction conditions, and reduced waste generation. These early-stage innovations represent a crucial step toward minimizing the environmental footprint of pharmaceutical development. As discoveries transition from laboratory scale to pilot and industrial production 🏭, the environmental assessment becomes more complex. Metrics such as E-factor, Process Mass Intensity (PMI), carbon footprint, energy consumption, and wastewater treatment r...

 🌱🔬  Sustainable corrosion protection  has become a critical focus in modern materials science, especially for industrial metals like A36 steel exposed to aggressive acidic environments such as 1 M HCl. Traditional corrosion inhibitors often contain toxic chemicals that pose environmental and health risks. In response, researchers are now exploring eco-friendly alternatives derived from natural waste materials. One promising innovation is a  citrus peel–surfactant bio-hybrid system , which combines plant-based extracts with surface-active agents to create a highly efficient, green corrosion inhibitor. 🍊♻️ This approach not only reduces chemical hazards but also promotes waste valorization and circular economy principles. 🧪⚙️ The citrus peel extract contains rich phytochemicals such as flavonoids, limonene, and polyphenols that adsorb onto the steel surface, forming a protective molecular film. When integrated with a compatible surfactant, the bio-hybrid system en...

 Recent advances in the chemistry of  1,3-oxaselenolanes and 1,3-oxaselenoles  have significantly expanded the landscape of selenium-containing heterocycles in modern organic synthesis. These five-membered rings, incorporating both oxygen and selenium atoms, exhibit unique electronic and redox properties compared to their sulfur and oxygen analogues. In recent years, chemists have developed efficient synthetic strategies including transition-metal catalysis, electrophilic cyclization, and green chemistry approaches that improve yield, selectivity, and functional group tolerance. Such methodologies have made these previously less-explored scaffolds more accessible for structural diversification and mechanistic studies. The fused system benzo[d][1,3]oxaselenoles has attracted particular attention due to its enhanced stability and extended π-conjugation. Modern research highlights innovative annulation reactions, intramolecular cyclizations, and cascade processes that allow...

Mitochondrial transcription plays a crucial role in cellular energy production, as mitochondria contain their own DNA and transcriptional machinery. Traditionally, studying mitochondrial RNA synthesis in vitro relied on radioactive labeling techniques, which posed safety concerns, disposal challenges, and regulatory limitations. ⚠️🧪 Recent advances now offer a safer and more efficient alternative through click-chemistry–based detection methods, eliminating the need for hazardous radioactive isotopes while maintaining high sensitivity and accuracy. 🔬💡 Click chemistry enables the incorporation of modified nucleotides into newly synthesized mitochondrial RNA. These modified molecules contain bioorthogonal functional groups that can react selectively with fluorescent probes under mild conditions. The result is a rapid, highly specific labeling process that allows researchers to visualize and quantify transcription products using fluorescence instead of radiation. This approach enhances ...
