Property Insights of Siyry

The XLogP value of -2.3 indicates that Siyry is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 412.0 Ų indicates high polarity, suggesting Siyry may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Siyry has 15 hydrogen bond donor(s) and 15 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
