Self-introduction
My study focuses on Medicinal Chemistry developing a novel medicine. To put it into practice, my viewpoint is different from that of organic synthetic chemists in terms of considering solubility, patent availability, metabolism, toxicity of compounds. Contact me if you want to optimize compound structure and develop a new medicine.
