Property Insights of NCI 144-128

The XLogP value of 7.01712 indicates that NCI 144-128 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 213.42 Ų indicates high polarity, suggesting NCI 144-128 may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, NCI 144-128 has 6 hydrogen bond donor(s) and 14 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
