Property Insights of Semax

The XLogP value of -2.8 indicates that Semax is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 312.0 Ų indicates high polarity, suggesting Semax may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Semax has 8 hydrogen bond donor(s) and 13 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
