Inhibition of Mer and Axl kinases has been implicated as a potential way to improve the efficacy of current immuno-oncol. therapeutics by restoring the innate immune response in the tumor microenvironment. Highly selective dual Mer/Axl kinase inhibitors are required to validate this hypothesis. Starting from hits from a DNA-encoded library screen, we optimized an imidazo[1,2-a]pyridine series using structure-based compound design to improve potency and reduce lipophilicity, resulting in a highly selective in vivo probe compound 32. We demonstrated dose-dependent in vivo efficacy and target engagement in Mer- and Axl-dependent efficacy models using two structurally differentiated and selective dual Mer/Axl inhibitors. Addnl., in vivo efficacy was observed in a preclin. MC38 immuno-oncol. model in combination with anti-PD1 antibodies and ionizing radiation.

Dysregulation of anaplastic lymphoma kinase (ALK) has been detected in nonsmall cell lung cancer (NSCLC) in the form of EML4-ALK fusion. Secondary mutations opposing activity of the first-generation ALK inhibitor crizotinib came into existence, requiring mutation-targeting drug discovery for the powerful second-line treatment. In this study, we report 4-phenoxyquinoline-based inhibitors that overcome crizotinib resistance to ALK L1196M, discovered by the fragment-growing strategy. The protonation of 4-aminoquinoline core could interrupt the ability the N atom of quinoline to act as a hydrogen bond acceptor; therefore, the pK_a and calculated ionization pH values of relevant pyridine-based core moieties were carefully analyzed. The replacement of amine linkage with ether resulted in single-digit nanomolar range inhibitors. The inhibitors exhibited significant antiproliferative effects on H2228 CR crizotinib-resistant cells by decreasing PI3K/AKT and MAPK signaling. This work constitutes the first example for systematic investigation of the effect of ionization pH on activity in this system.

Ma, Chenyang;Besson, Claire research published 《 Precise control of the degree and regioselectivity of functionalization in nitro- and amino-functionalized di(trispyrazolylborato)iron(II) spin crossover complexes》, the research content is summarized as follows. Di(trispyrazolylborato)iron(II) ([Tp₂Fe]) complexes represent one of the most robust classes of spin-crossover complexes. Their stability renders them particularly suitable for integration in nanoscale devices, e.g. as sensors or information storage units. While prior studies of the functionalization of those derivatives have been focused on the electronic and steric effects of alkyl and -CF₃ groups in position 3, a pyrazole exchange reaction between nitropyrazole and either trispyrazolylborate or its iron complex allows the regioselective installation of nitro substituents in positions 3, 4 and 5 of the [Tp₂Fe] complexes. The degree of substitution can be varied from 1 to 4 functionalized pyrazoles per complex. The amine-functionalized analogs are accessed by reduction of the nitro analogs under hydrogen transfer conditions. With the exception of di- and tetra-3-NO₂ substituted complexes, all derivatives display spin crossover properties in the solid state, with transition temperatures ranging from 180 to 380 K and showing different degrees of abruptness but no hysteresis. The Slichter-Drickamer model was used to extract the empirical thermodn. transition parameters, allowing a systematic investigation of the influence of stoichiometry, position, and electronic nature of the substitution on the magnetic properties of the complexes. The steric effects dominate for substitution in position 3 but the electronic effects are significant for the other positions.

Lyu, Jiyuan;Claraz, Aurelie;Vitale, Maxime R.;Allain, Clemence;Masson, Geraldine research published 《 Preparation of Chiral Photosensitive Organocatalysts and Their Application for the Enantioselective Synthesis of 1,2-Diamines》, the research content is summarized as follows. Chiral phosphoric acid based organocatalysis and visible-light photocatalysis have both emerged as promising technologies for the sustainable production of fine chems. In this context, we have envisioned the design and the synthesis of a new class of chimeric catalytic entities that would feature both catalytic capabilities. Given their multitask nature, such catalysts would be particularly attractive for the development of new catalytic transformations, tandem processes in particular. Toward this goal, several BINOL-based chiral phosphoric acid backbones presenting one or two visible-light-sensitive thioxanthone moieties have been prepared and studied. The utility of these new photoactive chiral organocatalysts is then demonstrated in the enantioselective tandem three-component electrophilic amination of enecarbamates. Of note, the C₁-sym. organo/photocatalyst has shown a better catalytic activity than those presenting a C₂ symmetry.
