Property Insights of A-Denopterin

The XLogP value of -1.4 indicates that A-Denopterin is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 211.0 Ų indicates high polarity, suggesting A-Denopterin may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, A-Denopterin has 5 hydrogen bond donor(s) and 12 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
