The enzyme glutaminase-1 (GLS-1) has shown a clear and coherent implication in the progression and exacerbation of different aggressive tumors such as glioblastoma, hepatocarcinoma, pancreas, bone, and triple-negative breast cancer. Few chemotypes are currently available as selective GLS-1 inhibitors, and still, fewer of them are at the clinical stage. In the present paper, starting from a naturally-inspired antitumor compound library, metabolomics has been used to putatively identify the molecular mechanism underlying biological activity. GLS-1 was identified as a potential target. Biochemical analysis confirmed the hypothesis leading to the identification of a new hit compound acting as a GLS-1 selective inhibitor (IC50 = 3.96 ± 1.05 μM), compared to the GLS-2 isoform (IC50 = 12.90 ± 0.87 μM), with remarkable antitumor potency over different aggressive tumor cell lines. Molecular modelling studies revealed new insight into the drug-target interaction providing robust SAR clues for the rational hit-to-lead development. The approach undertaken underlines the wide potential of metabolomics applied to drug discovery, particularly in target identification and hit discovery following phenotype screening.

The design of multi-targeting ligands was developed in the last decades as an innovative therapeutic concept for Parkinson's disease (PD) and other neurodegenerative disorders. As the monoamine oxidase B (MAO B) and the histamine H3 receptor (H3R) are promising targets for dopaminergic regulation, we synthetized dual-targeting ligands (DTLs) as non-dopaminergic receptor approach for the treatment of PD. Three series of compounds were developed by attaching the H3R pharmacophore to indanone-related MAO B motifs, leading to development of MAO B/H3R DTLs. Among synthesized indanone DTLs, compounds bearing the 2-benzylidene-1-indanone core structure showed MAO B preferring inhibition capabilities along with nanomolar hH3R affinity. Substitution of C5 and C6 position of the 2-benzylidene-1-indanones with lipophilic substituents revealed three promising candidates exhibiting inhibitory potencies for MAO B with IC50 values ranging from 1931 nM to 276 nM and high affinities at hH3R (Ki 50 = 276 nM, hH3R Ki = 6.5 nM) showed highest preference for MAO B over MAO A (SI > 36). Interestingly, IC50 determinations after preincubation of enzyme and DTLs revealed also nanomolar MAO B potency for 3e (MAO B IC50 = 232 nM), a structural isomer of 3f, and 3d (MAO B IC50 = 541 nM), suggesting time-dependent inhibition modes. Reversibility of inhibition for all three compounds were confirmed by dilution studies in excess of substrate. Thus, indanone-substituted derivatives are promising lead structures for the design of MAO B/hH3R DTLs as novel therapeutic approach of PD therapy.

A series of the cyclopentadienyl and indenyl molybdenum compounds bearing alkylammonium functions [(η5-Cp′)Mo(CO)2(N,NL)][BF4]2 were synthesized and characterized by analytical and spectroscopic methods. The structures of [{η5-C5H4CH2CH2NH(CH2)5}Mo(CO)2(4,7-Ph2-phen)][BF4]2 (4,7-Ph2-phen = 4,7-diphenyl-1,10-phenanthroline) and [(η5-C9H6CH2CH2NHMe2)Mo(CO)2(phen)][BF4]2 (phen = 1,10-phenanthroline) were determined by X-ray crystallography. All of the synthesized compounds exhibit high activity against the human leukemia cell lines MOLT-4 and HL-60. They are approximately one order of magnitude more active than cisplatin. This study has proven that the modification of the outer coordination sphere of molybdenum complexes has a strong impact on their activity and may be successfully used for the design of new highly cytotoxic active species. A series of highly cytotoxic molybdenum(II) complexes are synthesized, and their activity against MOLT-4 and HL-60 leukemia cells is established.

Meisoindigo has been used as an indirubin substitute for the treatment of chronic myeloid leukemia (CML) for several years. In view of its poor solubility and erratic absorption, several investigations have focused on developing analogues with more desirable physicochemical profiles. Here, we investigated the structure-activity relationship (SAR) of meisoindigo with respect to its antiproliferative activity on leukemic K562 cells and found that appending a phenalkyl side chain onto the lactam NH resulted in analogues that retained good activity. Furthermore, analogues in which the phenyl ring was substituted with a basic heterocycle were significantly more soluble than meisoindigo while retaining acceptable antiproliferative profiles. The most promising analogue (E)-1-(2-(4-methylpiperazin-1-yl)ethyl)-[3,3′-biindolinylidene]-2,2′-dione (5-4) is more potent than meisoindigo across a panel of malignant cells, with at least 40 times greater solubility than meisoindigo, little or no tendency to aggregate in solution and capable of significantly extending the lifespans of animals with K562 induced xenografts. Mechanistically, it induced apoptotic cell death and disrupted the progression of K562 cells from the G1 to G2 phase. Taken together, our findings highlighted the feasibility of addressing the physicochemical deficits of the isoindigo scaffold by systematic modifications which was achieved without overt loss of growth inhibitory activity.
Bulk gold-catalyzed reactions of diazoalkanes with amines and O2 to give enamines
Zhou, Yibo,Angelici, Robert J.,Keith Woo
body text, p. 8 - 15 (2010/11/24)
Bulk gold powder, consisting of approximately 5-50 μm particles, catalyzes reactions of diazoalkanes E(H)C=N2, where E is CO 2Et or PhC(O), with amines R1R2NH and O 2 to give enamine products (R1R2N)(E)C=CH(E) in 58-94% yield. The reactions are proposed to occur by initial formation of surface-bound (E)(H)C: carbene groups that are attacked by nucleophilic amines. The enamine products are very different than those obtained in reactions catalyzed by homogeneous transition metal complexes. These reactions of diazoalkanes, amines, and O2 represent a new type of bulk gold-catalyzed reaction.
