Property Insights of Colistin A

The XLogP value of -2.8 indicates that Colistin A is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 491.0 Ų indicates high polarity, suggesting Colistin A may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Colistin A has 18 hydrogen bond donor(s) and 18 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
