The hydrophobic effect is associated with the successive replacement of water molecules in binding site a protein by groups ligand. Although assumed to be entropy-driven, large changes enthalpy and entropy are observed model system thermolysin. Structural features ultimately determine thermodynamics effect.

The discovery of potent, peptide site directed, tyrosine kinase inhibitors has remained an elusive goal. Herein we describe the two such clinical candidates that inhibit Src. Compound 1 is a phase 3 trial candidate likely to provide first in class topical treatment for actinic keratosis (AK) with good efficacy and dramatically less toxicity compared existing standard therapy. 2 malignant glioblastoma induces 30% long-term complete tumor remission animal models. strategy these compounds...

With a wheat germ purified human placental preparation, this compound inhibited insulin-stimulated autophosphorylation 95-kDa beta-subunit (IC50 = 200 microM). The ability phosphorylate exogenous peptide substrate, angiotensin II, also inhibited. Half-maximal inhibition basal IRTK activity found at...
Accurately predicting the binding affinity of ligands to their receptors by computational methods is one major challenges in structure-based drug design. One potentially significant errors these predictions common assumption that ligand contributions noncovalent interactions are additive. Herein we present data obtained from two separate series thrombin inhibitors containing hydrophobic side chains increasing size bind S3 pocket and with, or without, an adjacent amine engages a hydrogen bond...
Abstract Purpose: To investigate the antitumor effects of targeting Src and tubulin in mucinous ovarian carcinoma. Experimental Design: The vitro vivo molecular mechanisms KX-01, which inhibits pathway polymerization, were examined cancer models. Results: In studies using RMUG-S RMUG-L cell lines showed that KX-01 inhibited proliferation, induced apoptosis, arrested cycle at G2–M phase, enhanced cytotoxicity oxaliplatin KX-01–sensitive line, RMUG-S. significantly decreased tumor burden mouse...
Src kinase is elevated in breast tumors that are ER/PR negative and do not overexpress HER2, but clinical trials with inhibitors have shown little activity.

Ligand functional groups can modulate the contributions of one another to ligand-protein binding thermodynamics, producing either positive or negative cooperativity. Data presented for four thermolysin phosphonamidate inhibitors demonstrate that differential free energy and enthalpy caused by replacement a H with Me group, which binds in well-hydrated S2' pocket, are more favorable presence ligand carboxylate. The entropy is however less favorable. Dissection these thermodynamic parameters,...
Purpose KX-01 is a novel dual inhibitor of Src and tubulin. Unlike previous inhibitors that failed to show clinical benefit during treatment breast cancer, can potentially overcome the therapeutic limitations current through inhibition both The present study further evaluates activity mechanism in vitro vivo.

Small changes, big effects: Two thrombin inhibitors (see picture; R=cyclopentyl (1 a), R=cyclohexyl b)) were characterized thermodynamically and computationally to explain their identical binding constants. Surprisingly, the free energy of is achieved with different enthalpic entropic contributions plot).
