- Identification of potent ITK inhibitors through focused compound library design including structural information
-
A series of novel compound libraries inhibiting interleukin-2 inducible T cell kinase (ITK) were designed, synthesized and evaluated. In the first design cycle two library scaffolds were identified showing low micromolar inhibition of ITK. Further iterative design cycles including crystal structure information of ITK and structurally related kinases led to the identification of indolylindazole and indolylpyrazolopyridine compounds with low nanomolar ITK inhibition.

- Suzuki-type cross-coupling reaction of unprotected 3-iodoindazoles with pinacol vinyl boronate: An expeditive C-3 vinylation of indazoles under microwave irradiation
-
Herein we report an expeditive C-3 vinylation of unprotected 3-iodoindazoles under microwave irradiation. Ten C-5 substituted 3-vinylindazole derivatives, nine of them novel, were synthesized through this method, which proceeds in moderate to excellent yields starting from C-5 substituted 3-iodoindazole derivatives. In all cases, the C-3 vinylated derivative was the only isolated product. This methodology allows access to 3-vinylated indazoles selectively and directly without the need of N-protection. 3-Vinylindazoles could be interesting synthetic intermediates allowing access to biologically active molecules.

- 4-Aminoquinolone piperidine amides: Noncovalent inhibitors of DprE1 with long residence time and potent antimycobacterial activity
-
4-Aminoquinolone piperidine amides (AQs) were identified as a novel scaffold starting from a whole cell screen, with potent cidality on Mycobacterium tuberculosis (Mtb). Evaluation of the minimum inhibitory concentrations, followed by whole genome sequencing of mutants raised against AQs, identified decaprenylphosphoryl-β-d-ribose 2′-epimerase (DprE1) as the primary target responsible for the antitubercular activity. Mass spectrometry and enzyme kinetic studies indicated that AQs are noncovalent, reversible inhibitors of DprE1 with slow on rates and long residence times of ～100 min on the enzyme. In general, AQs have excellent leadlike properties and good in vitro secondary pharmacology profile. Although the scaffold started off as a single active compound with moderate potency from the whole cell screen, structure-activity relationship optimization of the scaffold led to compounds with potent DprE1 inhibition (IC50 10 nM) along with potent cellular activity (MIC = 60 nM) against Mtb.
