A new series of potential Akt1 inhibitors with indole scaffold were designed and synthesized. The antiproliferative activity against PC-3 cell line and enzyme inhibitory activity against Akt1 were evaluated. Among them, some compounds showed much more potent antiproliferative activity and stronger Akt1 inhibitory activity compared to the positive control of GSK690693. In particular, compound 19b exhibited the most potent inhibitory activity against Akt1 with inhibition rate of 70.3% at a concentration of 10?nm. Furthermore, compound 19b could dose dependently reduce the phosphorylation of the downstream GSK3β protein in the PC-3 cell line and displayed fivefold higher antiproliferative activity against PC-3 cell line with IC50 value of 3.1?±?0.1?μm than positive control (15.5?±?0.4?μm). Herein, compound 19b may serve as a promising lead for further optimization and development of novel Akt1 inhibitors based on an indole scaffold.

The cyclo-dipeptide substrates of the essential M. tuberculosis (Mtb) enzyme CYP121 were deconstructed into their component fragments and screened against the enzyme. A number of hits were identified, one of which exhibited an unexpected inhibitor-like binding mode. The inhibitory pharmacophore was elucidated, and fragment binding affinity was rapidly improved by synthetic elaboration guided by the structures of CYP121 substrates. The resulting inhibitors have low micromolar affinity, good predicted physicochemical properties and selectivity for CYP121 over other Mtb P450s. Spectroscopic characterisation of the inhibitors′ binding mode provides insight into the effect of weak nitrogen-donor ligands on the P450 heme, an improved understanding of factors governing CYP121–ligand recognition and speculation into the biological role of the enzyme for Mtb.

Herein, we describe the discovery and synthesis of a new series of 1,2,4,7-tetra-substituted indole derivatives as novel AKT inhibitors by optimization of a weak hit methyl 4-(2-aminoethoxy)-1H-indole-2-carboxylate (1). Both representative compounds 6a and 6o exhibited the most potent inhibitory activities against AKT1, with inhibition rates of 72.5% and 78.6%, respectively, at concentrations of 10 nM. In addition, compounds 6a and 6o also potently inhibited the phosphorylation of the downstream GSK3 protein and displayed slightly better anti-proliferative activities in a prostate cancer cell line.

3-(2-(3-Pyridinyl)thiazolidin-4-oyl)indoles, a Novel Series of Platelet Activating Factor Antagonists

(2RS,4R)-3-(2-(3-pyridinyl)thiazolidin-4-oyl)indoles represent a new class of potent, orally active antagonists of platelet activating factor (PAF). The compounds were prepared by acylation of the magnesium or zinc salts of substituted indoles with (2RS,4R)-2-(3-pyridinyl)-3-(tert-butoxycarbonyl)thiazolidin-4-oyl chloride. The 3-acylindole moiety functions as a hydrolytically stabilized and conformationally restricted anilide replacement, which imparts a considerable boost in potency to the series. Structure-activity relationships observed for substitution on the indole ring system are discussed. Members of the series compare favorably with other reported PAF antagonists.
