Design, synthesis, and biological activity of Plastoquinone analogs as a new class of anticancer agents

In this paper, based on Plastoquinone (PQ) analogs possessing substituted aniline containing alkoxy group(s), new 2,3-dimethyl-5-amino-1,4-benzoquinones (PQ1-15) were designed and synthesized in either two steps or one-pot reaction. Specifically, the substituted amino moiety containing mono or poly alkoxy group(s) with various positions and groups were mainly explored to understand the structure-activity relationships for the cytotoxic activity against three human cancer cell lines (K562, Jurkat, and MT-2) and human peripheral blood mononuclear cells (PBMC). PQ2 was found to be most effective anticancer compound on K562 and Jurkat cell lines with IC50 values of 6.40 ± 1.73 muM and 7.72 ± 1.49 muM, respectively. Interestingly, the compound was non-cytotoxic to normal PBMC and also MT-2 cancer cells. PQ2 which showed significant selectivity in MTT assay was chosen for apoptotic/necrotic evaluation and results exhibited that it induced apoptosis in K562 cell line after 6 h of treatment. PQ2 showed anti-Abelson kinase 1 (Abl1) activity with different inhibitory profile than Imatinib in the panel of eight kinases. The binding mode of PQ2 into Abl ATP binding pocket was predicted in silico showing the formation of some key interactions. In addition, PQ2 induced Bcr-Abl1 mediated ERK pathway in human chronic myelogenous leukemia (CML) cells. Furthermore, DNA-cleaving capability of PQ2 was clearly enhanced by iron (II) complex system. Afterward, a further in silico ADMET prediction revealed that PQ2 possesses desirable drug-like properties and favorable safety profile. These results indicated that PQ2 has multiple mechanism of action and two of them are anti-Bcr-Abl1 and DNA-cleaving activity. This study suggests that Plastoquinone analogs could be potential candidates for multi-target anticancer therapy.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Rh/Cu-Catalyzed Ketone beta-Functionalization by Merging Ketone Dehydrogenation and Carboxyl-Directed C-H Alkylation

An efficient Rh/Cu-catalyzed method has been developed for the direct beta-arylation or alkenylation of ketones using (hetero)aryl or alkenyl carboxylic acids as coupling partners. This direct ketone beta-functionalization reaction proceeded via the merging of Cu-catalyzed ketone dehydrogenative desaturation and Rh-catalyzed carboxyl-directed C-H alkylation, exhibiting a broad substrate scope for both coupling partners. TEMPO proved to be essential for both dehydrogenation process and generation of the active Rh catalyst for C-H activation.

Pharmacological evaluation of prazosin- and doxazosin-related compounds with modified piperazine ring

New doxazosin-related compound (1-3) with a N,N’-dimethyl alkanediamine chain replacing the piperazine ring, have been synthesized and their pharmacological properties have been tested together with some prazosin analogues (4-8) bearing either a similar structural modification or a substituted piperazine moiety. In the in vitro study, on alpha1- and alpha2-adrenoceptors of rat vas deferens tissues, 1-3 displayed high alpha1-antagonist activity, 2 and 3 being equipotent to doxazosin but markedly less selective in respect to alpha2-adrenoceptors. Replacement of the piperazine ring with an alkanediamine chain resulted in a strong fall in alpha1-selectivity, owing to increased alpha2-antagonist activity, as in the prazosin-related series. In in vivo studies, the antihypertensive activity of tested compounds was investigated on spontaneously hypertensive rats (SHR) following both intragastric (IG) and intraperitoneal (OP) administration. Among the tested compounds, 7 and 8, which conserved a substituted piperazine ring, proved the most interesting drugs displaying a marked hypotensive effect. The other prazosin- and doxazosin-related compounds, in which an alkanediamine chain replaced the piperazine nucleus, showed an antihypertensive activity markedly lower than that of parent compounds, prazosin (CAS 19216-56-9) and doxazosin (CAS 74191-85-8), although a high alpha1-antagonist activity in in vitro tests was conserved. These results suggest that the piperazine ring of the prazosin- and doxazosin-related compounds, although not crucial for alpha1-antagonist activity, may play an important role in the antihypertensive effect, probably by influencing the pharmacokinetic properties of the antagonist.

Parallel synthesis of a library of bidentate protein tyrosine phosphatase inhibitors based on the alpha-ketoacid motif

Protein tyrosine phosphatases (PTPases) regulate intracellular signal transduction pathways by controlling the level of tyrosine phosphorylation in cells. These enzymes play an important role in a variety of diseases including type II diabetes and infection by the bacterium Yersinia pestis, which is the causative agent of bubonic plague. This report describes the synthesis, using parallel solution-phase methods, of a library of 104 potential inhibitors of PTPases. The library members are based on the bis(aryl alpha-ketocarboxylic acid) motif that incorporates a carboxylic acid on the central benzene linker. This carboxylic acid was coupled with a variety of different aromatic amines through an amide linkage. The aromatic component of the resulting amides is designed to make contacts with residues that surround the active site of the PTPase. The library was screened against the Yersinia PTPase and PTP1B. Based upon the screening results, four members of the library were selected for further study. These four compounds were evaluated against the Yersinia PTPase, PTP1B, TCPTP, CD45, and LAR. Compound 14 has an IC50 value of 590nM against PTP1B and is a reversible competitive inhibitor. This affinity represents a greater than 120-fold increase in potency over compound 2, the parent structure upon which the library was based. A second inhibitor, compound 12, has an IC50 value of 240nM against the Yersinia PTPase. In general, the selectivity of the inhibitors for PTP1B was good compared to LAR, but modest when compared to TCPTP and CD45.
