Property Insights of Day8Ra

The XLogP value of 0.2 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Day8Ra. The TPSA of 409.0 Ų indicates high polarity, suggesting Day8Ra may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Day8Ra has 12 hydrogen bond donor(s) and 12 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
