Kassab AE. Anticancer agents incorporating the N-acylhydrazone scaffold: Progress from 2017 to present. Arch Pharm (Weinheim) 2023; 356:e2200548. [PMID: 36638264 DOI: 10.1002/ardp.202200548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 12/20/2022] [Accepted: 12/23/2022] [Indexed: 01/15/2023]
Abstract
The N-acylhydrazone motif has been shown to be particularly adaptable and promising in the area of medicinal chemistry and drug development, due to its significant biological and pharmacological characteristics. Moreover, N-acylhydrazones are appealing synthetic and biological tools because of their simple and straightforward synthesis. This scaffold has emerged as a fundamental building block for the synthesis of bioactive compounds. Particularly, the N-acylhydrazone scaffold served as a base for the synthesis of a number of potent anticancer agents acting via different mechanisms. An updated summary of the anticancer activity of N-acylhydrazone derivatives described in the literature (from 2017 to 2022) is provided in the current review. It discusses the structure-activity relationship (SAR) of N-acylhydrazone derivatives exhibiting anticancer potential, which could be helpful in designing and developing new derivatives as effective antiproliferative candidates in the future.

Abstract
A novel platinum(II) complex 47OMESS(II) and its platinum(IV) derivative 47OMESS(IV) were synthesized and characterized. Cytotoxicity studies against mesenchymal cells (MCs) and lung (A549), breast (MDA-MB-231), and melanoma (A375) cancer cells demonstrated 7-20-fold superior activity for both complexes relative to cisplatin. Remarkably, 47OMESS(IV) demonstrated 17-22-fold greater selectivity toward the cancerous cells compared to the non-cancerous MCs. Western blot analysis on A549 cells showed the involvement of the intrinsic apoptotic pathway. Cellular fractionation and uptake experiments in A549 cells using ICP-mass spectrometry (MS) indicated that 47OMESS(II) and 47OMESS(IV) cross the cellular membrane predominantly via active transport mechanisms. The significant improvement in selectivity that is exhibited by 47OMESS(IV) is reported for the first time for this class of complexes.

Seed oil of Brucea javanica induces apoptosis through the PI3K/Akt signaling pathway in acute lymphocytic leukemia Jurkat cells. Chin J Nat Med 2021; 19:608-620.

Abstract
Brucea javanica oil emulsion (BJOE) has been used to treat tumor in China for more than 40 years. However, its components and effectiveness in the treatment of acute lymphocytic leukemia (ALL) and its mechanism of anti-cancer activity remain unknown. In the current study, high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD) was used to analyze the components of BJOE. Then, the anti-leukemia effects of BJOE were examined both in vitro and in vivo using ALL Jurkat cells and the p388 mouse leukemia transplant model, respectively. The primary ALL leukemia cells were also used to confirm the anti-leukemia effects of BJOE. The apoptotic-related results indicated that BJOE induced apoptosis in Jurkat cells and were suggestive of intrinsic apoptotic induction. Moreover, BJOE inhibited Akt (protein kinase B) activation and upregulated its downstream targets p53 and FoxO1 (forkhead box gene, group O-1) to initiate apoptosis. The activation of GSK3β was also involved. Our findings demonstrate that BJOE has anti-leukemia effects on ALL cells and can induce apoptosis in Jurkat cells through the phosphoinositide3-kinase (PI3K) /Akt signaling pathway.

Abstract
Caspases, a group of protease enzymes (cysteine proteases), exist as inactive zymogens in the cells and execute apoptosis (programmed cell death). Caspase-3, an executioner caspase, plays an imperative role in apoptosis and becomes a primary target for cancer treatment. A number of analogues of quinazoline, quinazolinone, indoloquinazolines, quinone, naphthoquinones, pyrroloiminoquinones, styrylquinolines, tetheredtetrahydroquinoline, fluoroquinolone, thiosemicarbazones, benzotriazole, pyrimidines, chalcone, and carbazoles have been reported till date, representing caspase-3 mediated apoptosis for cancer therapy. Simultaneously, plant isolates, including lysicamine, podophyllotoxin, and majoranolide, have also been claimed for caspase-3-mediated apoptosis-induced cytotoxicity. Procaspase-activating compound-1 (PAC-1) is the first FDA approved orphan drug, and its synthetic derivative WF-208 also showed fascinating caspase-3 mediated anticancer activity. Till date, a large number of compounds have been reported and patented for their caspase-3-mediated cytotoxicity and now scientist is also focusing to introduce new compounds in market to encompass anticancer activity.

Abstract
In continuity of our search for novel anticancer agents acting as procaspase activators, we have designed and synthesised two series of (E)-N′-benzylidene-carbohydrazides (4a–m) and (Z)-N'-(2-oxoindolin-3-ylidene)carbohydrazides (5a–g) incorporating 1-(4-chlorobenzyl)-1H-indole core. Bioevaluation showed that the compounds, especially compounds in series 4a–m, exhibited potent cytotoxicity against three human cancer cell lines (SW620, colon cancer; PC-3, prostate cancer; NCI-H23, lung cancer). Within series 4a–m, compounds with 2-OH substituent (4g–i) exhibited very strong cytotoxicity in three human cancer cell lines assayed with IC50 values in the range of 0.56–0.83 µM. In particular, two compounds 4d and 4f bearing 4-Cl and 4-NO2 substituents, respectively, were the most potent in term of cytotoxicity with IC50 values of 0.011–0.001 µM. In caspase activation assay, compounds 4b and 4f were found to activate caspase activity by 314.3 and 270.7% relative to PAC-1. This investigation has demonstrated the potential of these simple acetohydrazides, especially compounds 4b, 4d, and 4f, as anticancer agents.

Abstract
OBJECTIVES The in vitro evaluation of new drugs is an important step in the drug development pipeline. Orbitazine is a derivative of PAC-1 that has substituted the functional group homopiperazine ring with a piperazine ring. The purpose of this study was to assess the metabolic profile of orbitazine. METHODS Metabolism was characterized in vitro by incubating liver microsomes with metabolize orbitazine or the classical metabolic enzyme substrates. High performance liquid chromatography (HPLC) and LC-MS/MS were used to identify the parent drugs and metabolites of orbitazine or metabolic enzyme substrates. KEY FINDINGS There was no difference in metabolic stability or metabolites across different species. The metabolites included a debenzyl compound and several hydroxyl compounds, defined as M1(316), M2(440), M3(422), M4(422) and M5(422). We found that orbitazine was metabolized by CYP3A4, CYP2C9 and CYP2D6 in a human liver microsomes incubation system. Orbitazine had no significant inhibitory effect on CYP1A2, CYP2B6, CYP2C9, or CYP2C19 in human liver microsomes, but showed a dose-dependent inhibition of CYP2C8, CYP2D6 and CYP3A4; and there was no orbitazine-mediated induction of CYP1A2, CYP2B6, CYP3A4 or mRNA expression in hepatocytes. CONCLUSIONS This in vitro data on the metabolism of orbitazine may provide valuable information to support further clinical progression as a potential therapeutic molecule.

Abstract
Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy.

Abstract
Ninety-seven percent of drug-indication pairs that are tested in clinical trials in oncology never advance to receive U.S. Food and Drug Administration approval. While lack of efficacy and dose-limiting toxicities are the most common causes of trial failure, the reason(s) why so many new drugs encounter these problems is not well understood. Using CRISPR-Cas9 mutagenesis, we investigated a set of cancer drugs and drug targets in various stages of clinical testing. We show that-contrary to previous reports obtained predominantly with RNA interference and small-molecule inhibitors-the proteins ostensibly targeted by these drugs are nonessential for cancer cell proliferation. Moreover, the efficacy of each drug that we tested was unaffected by the loss of its putative target, indicating that these compounds kill cells via off-target effects. By applying a genetic target-deconvolution strategy, we found that the mischaracterized anticancer agent OTS964 is actually a potent inhibitor of the cyclin-dependent kinase CDK11 and that multiple cancer types are addicted to CDK11 expression. We suggest that stringent genetic validation of the mechanism of action of cancer drugs in the preclinical setting may decrease the number of therapies tested in human patients that fail to provide any clinical benefit.

Abstract
Novel 1,1-disubstituted cyclohexane-1-carboxamides 6a-h, 7a-e, and 8a-b were designed and synthesized as apoptotic inducers. Cytotoxicity test revealed that some compounds have strong to moderate effect, while others displayed weak action against different cancer cell lines including, MCF-7, HepG2, A549, and HTC-116. A549 carcinoma cell line exhibited higher sensitivity toward all synthesized candidates especially compounds 6a and 8a which offered the lowest IC50 values 3.03 and 5.21 μM, respectively, relative to the positive control doxorubicin with IC50 value of 3.01 μM. Compared to doxorubicin treatment, compounds 6a and 8a induced caspases-3, -8, and -9 activities and G2/M growth arrest in A549 carcinoma cell line. The expression levels of p53 (tumor suppressor protein that in humans is encoded by the TP53 gene), Bax (apoptosis regulator protein in humans that is encoded by bax gene), and the Bax/Bcl-2 ratio were all higher than those in doxorubicin-treated cells (Bcl-2, B-cell lymphoma 2, encoded in humans by the Bcl-2 gene). Additionally, compounds 6a and 8a appeared to exhibit higher selectivity against MCF-10 human breast normal cell line. The synthesized congeners could be considered as potent apoptotic inducers interfering with extrinsic and intrinsic apoptotic pathways. Moreover, compound 6a was able to form complex with zinc ions as indicated by UV spectrophotometry which revealed its ability for being caspase activator. Molecular docking studies expected the interactions and binding modes of the synthesized inhibitors in the caspase-3 active site.

Abstract
Background:
In this study, novel ortho-hydroxy N-acyl hydrazone moiety including
compounds (3a-l) were designed, based on procaspase activating compound (PAC-1) which is a
small molecule known with antitumor activity. The antitumor activity was evaluated on A549 (human
lung cancer cell line) and CCD 19Lu (human lung normal cell line).
Methods:
Twelve N'-arylidene-2-[4-(methylsulfonyl)piperazin-1-yl]acetohydrazide derivatives
(3a-l) were synthesized starting from ethyl 1-piperazinylacetate. All compounds were tested using
MTT method and Xcelligence-Real time cell analysis system (RTCA DP) to determine their antitumor
activity.
Results:
Some physicochemical properties of four active compounds were also predicted using
MolSoft, PreADMET and PROTOX software. Four of them, 3h, 3j, 3k and 3l bearing 3-hydroxy,
4-dimethylamino, 2,6-dichloro and 3,4-dichloro substituents in order exhibited selective cytotoxicity.
Conclusion:
Eligible values were obtained in the specified ranges as to be an oral/intravenous drug
considering the physicochemical calculations.

Abstract
Purpose Glioblastoma is a deadly brain cancer with a median survival time of ∼15 months. Ionizing radiation plus the DNA alkylator temozolomide (TMZ) is the current standard therapy. PAC-1, a procaspase-3 activating small molecule, is blood-brain barrier penetrant and has previously demonstrated ability to synergize with diverse pro-apoptotic chemotherapeutics. We studied if PAC-1 could enhance the activity of TMZ, and whether addition of PAC-1 to standard treatment would be feasible in spontaneous canine malignant gliomas. Experimental Design Using cell lines and online gene expression data, we identified procaspase-3 as a potential molecular target for most glioblastomas. We investigated PAC-1 as a single agent and in combination with TMZ against glioma cells in culture and in orthotopic rodent models of glioma. Three dogs with spontaneous gliomas were treated with an analogous human glioblastoma treatment protocol, with concurrent PAC-1. Results Procaspase-3 is expressed in gliomas, with higher gene expression correlating with increased tumor grade and decreased prognosis. PAC-1 is cytotoxic to glioma cells in culture and active in orthotopic rodent glioma models. PAC-1 added to TMZ treatments in cell culture increases apoptotic death, and the combination significantly increases survival in orthotopic glioma models. Addition of PAC-1 to TMZ and radiation was well-tolerated in 3 out of 3 pet dogs with spontaneous glioma, and partial to complete tumor reductions were observed. Conclusions Procaspase-3 is a clinically relevant target for treatment of glioblastoma. Synergistic activity of PAC-1/TMZ in rodent models and the demonstration of feasibility of the combined regime in canine patients suggest potential for PAC-1 in the treatment of glioblastoma.

Abstract
PURPOSE To develop more potent procaspase-3 activator, 7 novel derivatives of PAC-1 were synthesized and evaluated. Among them, SM-1 stood out for its promising activity and good pharmacokinetics properties. The purpose of this study is to elucidate the pharmacological mechanism of SM-1 and evaluate its efficacy and toxicity in-depth. METHODS To reveal the effects of SM-1 on caspase-3 activity, both in vitro activation assay and in cells fluorometric assay were tested. The protein levels and distributions of procaspase-3 and cleaved caspase-3 were also measured by western blot and immunostaining. MTT assay, apoptosis assay and mouse xenograft model were applied to evaluate the efficacy of SM-1. Preliminary safety assessments also tested the acute toxicity and tissue distribution of SM-1. RESULTS Compared to PAC-1, SM-1 showed higher cytotoxicity in cancer cells. Further investigation demonstrated that SM-1 relieved zinc-mediated inhibition of procaspase-3 and activated the caspase-3 activity both in tube test and in cells. Efficacy evaluation showed SM-1-induced cell apoptosis mainly via activation of caspase-3 and reduced tumor size in mouse xenograft model. Its apoptosis induction efficacy was higher than PAC-1. The preliminary safety assessment demonstrated that the overall LD50 of SM-1 lied between 500 and 1000 mg/kg and the distribution of SM-1 in brain was low. CONCLUSIONS We identified SM-1 as a promising antitumor candidate, which displayed enhanced procaspase-3 activating activity and potent cytotoxicity for cancer cells but low toxicity for normal cells.

Abstract
PAC-1 induces the activation of procaspase-3 in vitro and in cell culture by chelation of inhibitory labile zinc ions via its ortho-hydroxy-N-acylhydrazone moiety. First reported in 2006, PAC-1 has shown promise in cell culture and animal models of cancer, and a Phase I clinical trial in cancer patients began in March 2015 (NCT02355535). Because of the considerable interest in this compound and a well-defined structure-activity relationship, over 1000 PAC-1 derivatives have been synthesized in an effort to vary pharmacological properties such as potency and pharmacokinetics. This article provides a comprehensive examination of all PAC-1 derivatives reported to date. A survey of PAC-1 derivative libraries is provided, with an indepth discussion of four derivatives on which extensive studies have been performed.

Abstract
Procaspase-activating compound 1 (PAC-1) is an o-hydroxy-N-acylhydrazone that induces apoptosis in cancer cells by chelation of labile inhibitory zinc from procaspase-3. PAC-1 has been assessed in a wide variety of cell culture experiments and in vivo models of cancer, with promising results, and a phase 1 clinical trial in cancer patients has been initiated (NCT02355535). For certain applications, however, the in vivo half-life of PAC-1 could be limiting. Thus, with the goal of developing a compound with enhanced metabolic stability, a series of PAC-1 analogues were designed containing modifications that systematically block sites of metabolic vulnerability. Evaluation of the library of compounds identified four potentially superior candidates with comparable anticancer activity in cell culture, enhanced metabolic stability in liver microsomes, and improved tolerability in mice. In head-to-head experiments with PAC-1, pharmacokinetic evaluation in mice demonstrated extended elimination half-lives and greater area under the curve values for each of the four compounds, suggesting them as promising candidates for further development.
