Identification of low-dose, low-molecular-weight, drug-like inhibitors of protein-protein interactions (PPIs) is a challenging area of research. Despite the challenges, the therapeutic potential of PPI inhibition has driven significant efforts toward this goal. Adding to recent success in this area, we describe herein our efforts to optimize a novel purine carboxylic acid-derived inhibitor of the HDM2-p53 PPI into a series of low-projected dose inhibitors with overall favorable pharmacokinetic and physical properties. Ultimately, a strategy focused on leveraging known binding hot spots coupled with biostructural information to guide the design of conformationally constrained analogs and a focus on efficiency metrics led to the discovery of MK-4688 (compound 56), a highly potent, selective, and low-molecular-weight inhibitor suitable for clinical investigation.

Cycloalkylmethyl Radicals. Part 3. Dynamic Stereochemistry of Axial and Equatorial Cyclohexylmethyl and 4-Alkylcyclohexylmethyl Radicals
Ingold, Keith U.,Walton, John C.

For cyclohexylmethyl and 4-alkylcyclohexylmethyl radicals the conformer in which the CH2. group adopts the axial position and that in which the CH2. group adopts the equatorial position can both be observed by e.s.r. spectroscopy.At 140 K the axial conformers have a(Hβ) ca. 42-43 G; the equatorial conformers have a(Hβ) ca. 30-31 G.For cis-4-methylcyclohexylmethyl radicals the ratio of the concentrations of the two conformers was studied as a function of temperature and shown to depend on the rate of radical ring inversion vs. the radical lifetime; the rate constant for ring inversion was obtained.As a check on the e.s.r. results the conformational equilibrium of cis-4-methylcyclohexylmethyl bromide was studied by 1H n.m.r. spectroscopy, which gave -ΔG0300(CH2Br) = 1.91 kcal mol-1.The relative conformer concentrations were also measured as a function of temperature for cyclohexylmethyl radicals and the conformational free energy difference of the CH2. group (-ΔG0300) was found to be 0.71 kcal mol-1.The preponderance of the conformer of the cis-4-methylcyclohexylmethyl radical with the CH3 group axial at T . group cannot because of its planarity.The barriers to rotation about the Cα-Cβ bonds in the axial radicals were found to be ca. 1.0 kcal mol-1 greater than those of the equatorial radicals; this is responsible for the greater a(Hβ) values of the axial radicals.The axial and equatorial conformers of cyclohexylmethyl radicals were investigated by semi-empirical SCF MO-methods.
The Properties of Liquid Crystal Materials Incorporating the -CH2O- Inter-ring Linkage
Carr, N.,Gray, G. W.
, p. 27 - 44 (2007/10/02)
To establish more securely the influence of the -CH2O- inter-ring linkage upon the properties of mesogens of both high and low dielectric anisotropy, a range of ethers with the following general structure has been prepared and their properties examined. The thermal and electro-optic properties of the compounds are discussed, and comparisons made where possible with analogous materials incorporating the -CH2CH2- linkage.
