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.

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.

M.;Cano, Celine research published 《 Parallel Optimization of Potency and Pharmacokinetics Leading to the Discovery of a Pyrrole Carboxamide ERK5 Kinase Domain Inhibitor》, the research content is summarized as follows. The nonclassical extracellular signal-related kinase 5 (ERK5) mitogen-activated protein kinase pathway has been implicated in increased cellular proliferation, migration, survival, and angiogenesis; hence, ERK5 inhibition may be an attractive approach for cancer treatment. However, the development of selective ERK5 inhibitors has been challenging. Previously, we described the development of a pyrrole carboxamide high-throughput screening hit into a selective, submicromolar inhibitor of ERK5 kinase activity. Improvement in the ERK5 potency was necessary for the identification of a tool ERK5 inhibitor for target validation studies. Herein, we describe the optimization of this series to identify nanomolar pyrrole carboxamide inhibitors of ERK5 incorporating a basic center, which suffered from poor oral bioavailability. Parallel optimization of potency and in vitro pharmacokinetic parameters led to the identification of a nonbasic pyrazole analog with an optimal balance of ERK5 inhibition and oral exposure.

Concurrent inhibition of Janus kinase (JAK) and histone deacetylase (HDAC) could potentially improve the efficacy of the HDAC inhibitors in the treatment of cancers and resolve the problem of HDAC inhibitor resistance in some tumors. Here, a novel series of pyrimidin-2-amino-pyrazol hydroxamate derivatives as JAK and HDAC dual inhibitors was designed, synthesized, and evaluated, among which I possessed potent and balanced activities against both JAK2 and HDAC6 with half-maximal inhibitory concentration at the nanomolar level. I exhibited improved antiproliferative and proapoptotic activities over SAHA and ruxolitinib in several hematol. cell lines. Remarkably, I exhibited more potent antiproliferation effect than the combination of SAHA and ruxolitinib in HEL cells bearing JAK2^V617F mutation. Pharmacokinetic studies in mice showed that I possessed good bioavailability after i.p. administration. Finally, I showed antitumor efficacy with no significant toxicity in a HEL xenograft model. Collectively, the results confirm the therapeutic potential of JAK and HDAC dual inhibitors in hematol. malignancies and provide valuable leads for further structural optimization and antitumor mechanism study.

It remains a big challenge to develop HDAC inhibitors effective for solid tumors. Previous studies have suggested that the feedback activation of JAK-STAT3 pathway represents a key mechanism leading to resistance to HDAC inhibitors in breast cancer, suggesting the therapeutic promise of JAK/HDAC dual inhibitors. In this work, we discovered a series of pyrrolo[2,3-d]pyrimidine-based derivatives as potent JAK and HDAC dual inhibitors. Especially, compounds 15d and 15h potently inhibited JAK1/2/3 and HDAC1/6 and displayed antiproliferative and proapoptotic activities in triple-neg. breast cancer cell lines. Besides, compounds 15d and 15h also diminished the activation of LIFR-JAK-STAT signaling triggered by tumor-associated fibroblasts, which suggests that these compounds could potentially overcome the drug resistance caused by the tumor microenvironment. More importantly, compound 15d effectively inhibited the tumor growth in MDA-MB-231 xenograft tumor model. Overall, this work provides valuable leads and novel antitumor mechanisms for the treatment of the SAHA-resistant triple-neg. breast cancers.

The solubility of 4-nitropyrazole (4-NP) in four different binary solvents (i.e., water + n-butanol, water + n-pentanol, water + isobutanol, and water + isoamyl alc.) was firstly determined by a gravimetric method within a temperature range of 288.15 K to 328.15 K at atm. pressure (P = 0.1 MPa). The exptl. results indicated that the solubility of 4-NP in selected binary solvents increases with the increasing temperature and decreases with the rising water mass-fraction ranging. Besides, the (solid + liquid) equilibrium values in the studied solvents were correlated based on the modified Apelblat equation, Jouyban-Acree model, CNIBS/R-K model, and Wilson model. Moreover, all of the 324 exptl. values were used to correlate the parameters of the Wilson model, and the correlated results were superior to the other three models by comparing the average 10⁴RMSD and R². The average root-mean-square deviation (10⁴RMSD) values were 1.87, 31.83, 6.04, and 1.18, resp. In addition, Hansen solubility parameters were employed to provide a reasonable illustration for the solubility order of 4-NP in the 4 binary mixed solvents, and the order of 4-NP solubility in each binary solvent mixture was the result of the combined effects of hydrogen bonding, dispersion, and polarity. Furthermore, the Wilson model was applied to calculate the thermodn. properties of 4-NP including mixing enthalpy, mixing entropy, and mixing free Gibbs energy in the studied binary solvent mixtures at a given temperature It is easy to understand that dissolution is an exothermic process from the results. Solid-liquid surface tension (γ) and surface entropy factor (f) of 4-NP were estimated by using the exptl. solubility data, and the results showed that γ and f increase with the increasing mass-fraction of water content in the binary mixed solvent and decrease with the increasing temperature The exptl. solubility values, model parameters, and thermodn. properties of 4-NP in different mixed solvents will provide the necessary support for its preparation, crystallization process, and further theor. studies.
