John A Arnott et al.
Expert opinion on drug discovery, 7(10), 863-875 (2012-09-21)
The role of lipophilicity in drug discovery and design is a critical one. Lipophilicity is a key physicochemical property that plays a crucial role in determining ADMET (absorption, distribution, metabolism, excretion, and toxicity) properties and the overall suitability of drug
Cristian Gobbo et al.
ACS nano, 6(12), 10684-10698 (2012-12-12)
Controlling the molecular conformation of oligomers on surfaces through noncovalent interactions symbolizes an important approach in the bottom-up patterning of surfaces with nanoscale precision. Here we report on the design, synthesis, and scanning tunneling microscopy (STM) investigation of linear oligoamides
B D Anderson et al.
The Journal of investigative dermatology, 93(2), 280-286 (1989-08-01)
The permeability coefficients (kp) of a series of methyl-substituted p-cresols were determined in human stratum corneum along with their partition coefficients (PC) between water and untreated stratum corneum, delipidized stratum corneum, octanol, and heptane. The PC values were identical in
R O Potts et al.
Pharmaceutical research, 9(5), 663-669 (1992-05-01)
Published permeability coefficient (Kp) data for the transport of a large group of compounds through mammalian epidermis were analyzed by a simple model based upon permeant size [molecular volume (MV) or molecular weight (MW)] and octanol/water partition coefficient (Koct). The

Thymidine analogs containing o-carboranylalkyl groups at the 3-position were screened as potential substrates for human thymidine kinase 1 (TK1), an enzyme that is selectively expressed in a variety of rapidly proliferating cells, including tumor cells. On the basis of previous
