New class of pyridine catalyst having a conformation switch system: Asymmetric acylation of various sec-alcohols

We have developed a new class of pyridine catalyst for asymmetric acylation of sec-alcohols having a conformation switch system in which interconversion between self-complexation and uncomplexation is induced by acylation and deacylation steps, respectively. Kinetic resolution of various sec-alcohols is performed by the asymmetric acylation with isobutyric anhydride using 0.05 to 0.5 mol % catalyst 1a with s values of up to 30. In addition, dl-diols are also resolved in a similar manner in good selectivity. Moreover, asymmetric desymmetrization of meso-1,X-diols (X = 2-6) are achieved in the presence of 0.5-5 mol % catalyst 1a. A working model for the reaction mechanism is proposed on the basis of the 1H NMR measurements, X-ray structural analyses, and AM1 and DFT calculations, where the conformation switch system governed by an intramolecular cation-pi interaction between a pyridinium ring and a thiocarbonyl group would play a key role to attain both good selectivity and high catalytic activity.

Design, synthesis, and antiprotozoal evaluation of new 2,4-bis[(substituted-aminomethyl)phenyl]quinoline, 1,3-bis[(substituted-aminomethyl)phenyl]isoquinoline and 2,4-bis[(substituted-aminomethyl)phenyl]quinazoline derivatives

A series of new 2,4-bis[(substituted-aminomethyl)phenyl]quinoline, 1,3-bis[(substituted-aminomethyl)phenyl]isoquinoline, and 2,4-bis[(substituted-aminomethyl)phenyl]quinazoline derivatives was designed, synthesised, and evaluated in vitro against three protozoan parasites (Plasmodium falciparum, Leishmania donovani, and Trypanosoma brucei brucei). Biological results showed antiprotozoal activity with IC50 values in the muM range. In addition, the in vitro cytotoxicity of these original molecules was assessed with human HepG2 cells. The quinoline 1c was identified as the most potent antimalarial candidate with a ratio of cytotoxic to antiparasitic activities of 97 against the P. falciparum CQ-sensitive strain 3D7. The quinazoline 3h was also identified as the most potent trypanosomal candidate with a selectivity index (SI) of 43 on T. brucei brucei strain. Moreover, as the telomeres of the parasites P. falciparum and Trypanosoma are possible targets of this kind of nitrogen heterocyclic compounds, we have also investigated stabilisation of the Plasmodium and Trypanosoma telomeric G-quadruplexes by our best compounds through FRET melting assays.

Rad51/BRCA2 disruptors inhibit homologous recombination and synergize with olaparib in pancreatic cancer cells

Olaparib is a PARP inhibitor (PARPi). For patients bearing BRCA1 or BRCA2 mutations, olaparib is approved to treat ovarian cancer and in clinical trials to treat breast and pancreatic cancers. In BRCA2-defective patients, PARPi inhibits DNA single-strand break repair, while BRCA2 mutations hamper double-strand break repair. Recently, we identified a series of triazole derivatives that mimic BRCA2 mutations by disrupting the Rad51-BRCA2 interaction and thus double-strand break repair. Here, we have computationally designed, synthesized, and tested over 40 novel derivatives. Additionally, we designed and conducted novel biological assays to characterize how they disrupt the Rad51-BRCA2 interaction and inhibit double-strand break repair. These compounds synergized with olaparib to target pancreatic cancer cells with functional BRCA2. This supports the idea that small organic molecules can mimic genetic mutations to improve the profile of anticancer drugs for precision medicine. Moreover, this paradigm could be exploited in other genetic pathways to discover innovative anticancer targets and drug candidates.

Structure-Based Discovery and Development of a Series of Potent and Selective Bromodomain and Extra-Terminal Protein Inhibitors

BRD4 has recently emerged as a promising drug target. Therefore, identifying novel inhibitors with distinct properties could enrich their use in anticancer treatment. Guided by the cocrystal structure of hit compound 4 harboring a five-membered-ring linker motif, we quickly identified lead compound 7, which exhibited good antitumor effects in an MM.1S xenograft model by oral administration. Encouraged by its high potency and interesting scaffold, we performed further lead optimization to generate a novel potent series of bromodomain and extra-terminal (BET) inhibitors with a (1,2,4-triazol-5-yl)-3,4-dihydroquinoxalin-2(1H)-one structure. Among them, compound 19 was found to have the best balance of activity, stability, and antitumor efficacy. After confirming its low brain penetration, we conducted comprehensive preclinical studies, including a multiple-species pharmacokinetics profile, extensive cellular mechanism studies, hERG assay, and in vivo antitumor growth effect testing, and we found that compound 19 is a potential BET protein drug candidate for the treatment of cancer.

Three-dimensional quantitative structure-activity relationship analyses of substrates of the human proton-coupled amino acid transporter 1 (hPAT1)

The proton-coupled amino acid transporter hPAT1 has recently gained much interest due to its ability to transport small drugs thereby allowing their oral administration. A three-dimensional quantitative structure-activity relationship (3D QSAR) study has been performed on its natural and synthetic substrates employing comparative molecular similarity indices analysis (CoMSIA) to investigate the structural requirements for substrates and to derive a predictive model that may be used for the design of new prodrugs. The cross-validated CoMSIA models have been derived from a training set of 40 compounds and the predictive ability of the resulting models has been evaluated against a test set of 10 compounds. Despite the relatively narrow range of binding affinities (Ki values) reliable statistical models with good predictive power have been obtained. The best CoMSIA model in terms of a proper balance of all statistical terms and the overall contribution of individual properties has been obtained by considering steric, hydrophobic, hydrogen bond donor and acceptor descriptors (q2 cv = 0.683, r2 = 0.958 and r2 PRED = 0.666). The 3D QSAR model provides insight in the interactions between substrates and hPAT1 on the molecular level and allows the prediction of affinity constants of new compounds. A pharmacophore model has been generated from the training set by means of the MOE (molecular operating environment) program. This model has been used as a query for virtual screening to retrieve potential new substrates from the small-molecule, ‘leadlike’ databases of MOE. The affinities of the compounds were predicted and 11 compounds were identified as possible high-affinity substrates. Two selected compounds strongly inhibited the hPAT mediated L-[3H]proline uptake into Caco-2 cells constitutively expressing the transport protein.
