Property Insights of Colistin

The XLogP value of -5.8315 indicates that Colistin is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 490.66 Ų indicates high polarity, suggesting Colistin may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Colistin has 18 hydrogen bond donor(s) and 18 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
