Olaparib hydroxamic acid derivatives as dual PARP and HDAC inhibitors for cancer therapy

Olaparib was the first PARP inhibitor approved by the FDA for patients with BRCA-mutated ovarian cancer. Recent studies have demonstrated enhanced anticancer effects of combination therapy consisting of olaparib and HDAC inhibitors. Herein, based on rational drug design strategy, hydroxamic acid derivatives of olaparib were constructed as dual PARP and HDAC inhibitors. These hybrid compounds showed potent inhibitory activities against PARP1/2 and HDAC1/6 with IC50 values in the nanomolar range. Furthermore, compound P1 exhibited broad-spectrum antiproliferative activities in selected human cancer cell lines. Specially, P1 showed more potent activity than olaparib and SAHA in cancer cells MDA-MB-231, HCC1937 and Raji, and 4.1-fold less cytotoxicity compared with SAHA to normal cells MCF-10A. Further mechanism study indicated that P1 could induce the cleavage of PARP and the hyperacetylation of histones, increase the expression of DNA damage biomarker gamma-H2AX, decrease the level of BRCA1 and RAD51, and regulate tumor cell growth and apoptosis through modulating both mitochondrial- and death receptor-mediated pathways. Therefore, our study suggested that compounds targeting PARP and HDAC concurrently might be a practical approach for cancer therapy.

Rational design, green synthesis, and initial evaluation of a series of full-color tunable fluorescent dyes enabled by the copper-catalyzed N-arylation of 6-phenyl pyridazinones and their application in cell imaging

There is widespread interest in the application, optimization, and evolution of the transition-metal-catalyzed arylation of N-heteroarenes to discover full-color tunable fluorescent core frameworks. Inspired by the versatile roles of pyridazinone in organic synthesis and medicinal chemistry, herein, we report a simple and efficient copper-catalyzed cross-coupling reaction for the N-functionalization of pyridazinones in neat water. To achieve the efficient conversion of pyridazinones and organic halides in aqueous phase, a series of copper-salen complexes composed of different Schiff base ligands were investigated by rational design. A final choice of fine-tuned hydrophilicity balanced with lipophilicity among the candidates was confirmed, which affords excellent activity towards the reaction of a wide range of pyridazinones and organic halides. More importantly, the products as N-substituted pyridazinones were synthesized rationally by this methodology as full-color tunable fluorescent agents (426-612 nm). The N2 position of pyridazinones was modified by different aryl group such as benzothiazole, N,N-dimethylaniline, 3-quinoline, 4-isoquinoline and 2-thiophene, resulting in a series of full-color tunable fluorescent reagents. Meanwhile, the effects of electron-donating and electron-withdrawing groups of the 6-substituted phenyl ring have also been investigated to optimize the fluorescent properties. These fluorescent core frameworks were studied in several cell lines as fluorescent dyes. Different colors from blue to red were observed by using fluorescence microscopy and confocal microscopy. Colorful cores: A simple and efficient copper-catalyzed cross-coupling reaction for the N-functionalization of pyridazinones in neat water is reported (see figure). The N2 position of pyridazinones was modified by different aryl groups (R1), such as benzothiazole, N,N-dimethylaniline, 3-quinoline, 4-isoquinoline, and 2-thiophene, resulting in a series of full-color tunable fluorescent reagents.

Rhodium(III)-Catalyzed C-H Functionalization of 1-(2H)-Phthalazinones at C8

The rhodium(III) catalyst tris(acetonitrile)pentamethylcyclopentadienylrhodium(III) hexafluoroantimonate ([Cp*Rh(MeCN)3](SbF6)2) reacts with 1-(2H)-phthalazinones to promote a C-H functionalization event at C8. Preparation of a set of compounds arising from oxidative alkenylation with olefins, hydroarylation with alkynes, and iodination with N-iodosuccinimide is reported here. Oxidative alkenylation proceeds in very good yield, and the scope and limitations of the hydroarylation and halogenation reactions are discussed. Notably, this strategy enables rapid preparation of C8-substituted phthalazinones without requiring phthalazinone ring synthesis starting from a prefunctionalized arene.

Design, synthesis and anticancer activities of novel dual poly(ADP-ribose) polymerase-1/histone deacetylase-1 inhibitors

Currently, synergistic inhibition of poly(ADP-ribose) polymerase-1 (PARP-1) and histone deacetylases (HDACs) has been a potential effective strategy for cancer treatment. Herein, by combining critical pharmacophores in approved drugs olaparib and chidamide, a series of novel 2-fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid derivatives were designed and synthesized. All efforts led to a good dual PARP-1/HDAC-1 inhibitor, compound 4, with IC50 values of 4.2 and 340 nM against PARP-1 and HDAC-1, which were as potent as olaparib and chidamide respectively. The MTT assay further demonstrated that compound 4 had potent inhibitory activities against BRCA1/2-proficient K562 and MDA-MB-231 cells with GI50 values of 5.6 and 4.3 muM, respectively. Therefore, our results suggested that compound 4 could be a promising dual PARP-1/HDAC-1 inhibitor for further studies. In addition, a few excellent PARP-1 inhibitors such as 7?9 and HDAC-1 inhibitors such as 12 were serendipitously discovered, which also could be further studied in our next work.

Identification and preclinical characterization of a novel and potent poly?(ADP-ribose) polymerase (PARP) inhibitor ZYTP1

Purpose: Poly(ADP-ribose) polymerase-1 (PARP-1) is a nuclear enzyme involved in the detection and repair of DNA damage. Studies have shown that inhibition of PARP and Tankyrase (TNKS) has significant antitumor effect in several types of cancers including BRCA-negative breast cancers. Methods: Identification of ZYTP1, a novel PARP inhibitor, through a battery of in vitro assays and in vivo studies. PARP and TNKS inhibitory activity of ZYTP1 was assessed in cell-free kinase assay. In vitro cell killing potency of ZYTP1 was tested in a panel of cell lines including BRCA-negative cells. ZYTP1 was also tested in xenograft models in combination with temozolomide (TMZ). The pharmacokinetic profile of ZYTP1 was determined in rodent and non-rodent preclinical species. Safety of ZYTP1 was assessed in Wistar rats and Beagle dogs upon repeated dosing. Results: ZYTP1 inhibited PARP1, PARP2, Tankyrase-1 and Tankyrase-2 with IC50 of 5.4, 0.7, 133.3 and 289.8?nM, respectively, and additionally trapped PARP1 onto damaged DNA. It also potentiated MMS-mediated killing of different cancer cell lines. Compound demonstrated good Caco-2 cell permeability. The oral bioavailability of ZYTP1 in mice, rats and dogs ranged between 40 and 79% and demonstrated efficacy in colon cancer xenograft model at a dose of 1?10?mg/kg in combination with TMZ. In a 28-day repeat dosing, oral toxicity study in rats, it was found to show > 10¡Á safety margin. Conclusions: ZYTP1 is a novel PARP inhibitor that showed potential for development as a treatment for various solid tumors.
