We report structure-guided modifications of the benzyloxy substituent of the Insulin-like Growth Factor-1 Receptor (IGF-1R) inhibitor NVP-AEW541. This chemical group has been shown to confer selectivity against other protein kinases but at the expense of a metabolism liability. X-ray crystallography has revealed that the benzyloxy moiety interacts with a lysine cation of the IGF-1R kinase domain via its ether function and its aromatic pi-system and is nicely embedded in an induced hydrophobic pocket. We show that 1,4-diethers displaying an adequate hydrophobic and constrained shape are advantageous benzyloxy replacements. A single digit nanomolar inhibitor (compound 20, IC50 = 8.9 nM) was identified following this approach.

The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research.Keep reading other articles of 57203-01-7. category: Tetrahydrofurans

A new synthetic approach to C-2 triazole-linked bioconjugates of lupane triterpenoids with 3?-azido-3?- deoxythymidine (AZT) based on CuI-catalyzed 1,3-cycloaddition between alkynes and azides is described. The proposed strategy towards AZT-betulinic acid hybrid molecules as potential anti-HIV agents makes it possible to vary the C-3 and C-28 pharmacophores in triterpene moieties. The C-2 propargyl-substituted betulinic acid and its mono- or bi-functional derivatives with side chain at C-3 and/or C-28 positions were successfully synthesized by employing the click reaction.

A metabolism-based approach toward the optimization of a series of N-arylsulfonamide-based -secretase inhibitors is reported. The lead cyclohexyl analogue 6 suffered from extensive oxidation on the cycloalkyl motif by cytochrome P450 3A4, translating into poor human liver microsomal stability. Knowledge of the metabolic pathways of 6 triggered a structure activity relationship study aimed at lowering lipophilicity through the introduction of polarity. This effort led to several tetrahydropyran and tetrahydrofuran analogues, wherein the 3- and 4-substituted variants exhibited greater microsomal stability relative to their 2-substituted counterparts. Further reduction in lipophilicity led to the potent -secretase inhibitor and 3-substituted oxetane 1 with a reduced propensity toward oxidative metabolism, relative to its 2-substituted isomer. The slower rates of metabolism with 3-substituted cyclic ethers most likely originate from reductions in lipophilicity and/or unfavorable CYP active site interactions with the heteroatom. Preliminary animal pharmacology studies with a representative oxetane indicate that the series is generally capable of lowering A in vivo. As such, the study also illustrates the improvement in druglikeness of molecules through the use of the oxetane motif.
