- 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.

- On the tautomerism of cinnolin-4-ol, cinnoline-4-thiol, and cinnolin-4-amine
-
Detailed NMR spectroscopic investigations (1H, 13C, 15N) with cinnolin-4-ol (1) reveal this compound to exist exclusively in the cinnolin-4(1H)-one form in deuteriodimethyl sulfoxide solution. This finding is confirmed by comparison of the NMR spectroscopic data of 1 with those of the corresponding 'fixed' O-methyl and N-methyl derivatives, i.e. 4-methoxycinnoline (3) and 1-methylcinnolin-4(1H)-one (5). Similarly, cinnoline-4-thiol (4) is present in the thione form in deuteriodimethyl sulfoxide, whereas cinnolin-4-amine (7) exists in the amino form. In addition, in-depth analyses of the NMR spectra of some simple 4-substituted cinnolines are provided.

- Solid-phase synthesis of substituted cinnolines by a Richter type cleavage protocol
-
Starting from triazene bound ortho-halo arenes on a solid support, palladium-catalyzed alkynylations and subsequent cleavage reactions under acidic conditions give rise to ortho-alkynylaryldiazonium salts, which in turn undergo cyclization to afford substituted 4-halo- and 4- hydroxycinnolines in moderate to good yields. The method is applicable to automated synthesis.
