Abstract
Ecteinascidin 743 (Et-743), also known by the trade name Yondelis®, is the pioneering marine natural product to be successfully developed as an antitumor drug. Moreover, it is the first tetrahydroisoquinoline natural product used clinically for antitumor therapy since Kluepfel, a Canadian scientist, discovered the tetrahydroisoquinoline alkaloid (THIQ) naphthyridinomycin in 1974. Currently, almost a hundred natural products of bistetrahydroisoquinoline type have been reported. Majority of these bistetrahydroisoquinoline alkaloids exhibit diverse pharmacological activities, with some family members portraying potent antitumor activities such as Ecteinascidins, Renieramycins, Saframycins, Jorumycins, among others. Due to the unique chemical structure and exceptional biological activity of these natural alkaloids, coupled with their scarcity in nature, research seeking to provide material basis for further bioactivity research through total synthesis and obtaining compound leads with medicinal value through structural modification, remains a hot topic in the field of antitumor drug R&D. Despite the numerous reviews on the total synthesis of bistetrahydroisoquinoline natural products, comprehensive reviews on their structural modification are apparently scarce. Moreover, structural modification of bioactive natural products to acquire lead compounds with improved pharmaceutical characteristics, is a crucial approach for innovative drug discovery. This paper presents an up-to-date review of both structural modification and activity of bistetrahydroisoquinoline natural products. It highlights how such alkaloids can be used as antitumor lead compounds through careful chemical modifications. This review offers valuable scientific references for pharmaceutical chemists engaged in developing novel antitumor agents based on such alkaloid modifications, as well as those with such a goal in future.

[PMID: 36470328 DOI: 10.1016/j.phytochem.2022.113532] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 11/24/2022] [Accepted: 11/26/2022] [Indexed: 06/17/2023]
Abstract
Natural products can generally exhibit a variety of biological activities, but most show mediocre performance in preliminary activity evaluation. Natural products often require structural modification to obtain promising lead compounds. Cinnamic acid (CA) is readily available and has diverse biological activities and low cytotoxicity. Introducing CA into natural products may improve their performance, enhance biological activity, and reduce toxic side effect. Herein, we aimed to discuss related applications of CA in the structural modification of natural products and provide a theoretical basis for future derivatization and drug development of natural products. Published articles, web databases (PubMed, Science Direct, SCI Finder, and CNKI), and clinical trial websites (https://clinicaltrials.gov/) related to natural products and CA derivatives were included in the discussion. Based on the inclusion criteria, 128 studies were selected and discussed herein. Screening natural products of CA derivatives allowed for classification by their biological activities. The full text is organized according to the biological activities of the derivatives, with the following categories: anti-tumor, neuroprotective, anti-diabetic, anti-microbial, anti-parasitic, anti-oxidative, anti-inflammatory, and other activities. The biological activity of each CA derivative is discussed in detail. Notably, most derivatives exhibited enhanced biological activity and reduced cytotoxicity compared with the lead compound. CA has various advantages and can be widely used in the synthesis of natural product derivatives to enhance the properties of drug candidates or lead compounds.

New β-carboline derivatives containing imidazolium as potential VEGFR2 inhibitors: synthesis, X-ray structure, antiproliferative evaluations, and molecular modeling. RSC Med Chem 2022; 13:1064-1076. [PMID: 36324492 PMCID: PMC9491354 DOI: 10.1039/d2md00065b] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 06/12/2022] [Indexed: 09/19/2023] Open
Abstract
A series of new β-carboline derivatives containing an imidazolium moiety were designed and synthesized via the reaction of β-carboline-1-carboxaldehydes, acetyl chloride, primary amine, and formaldehyde. The antitumor activity of the synthesized compounds was examined against lung carcinoma (A549), gastric carcinoma (BGC-823), murine colon carcinoma (CT-26), liver carcinoma (Bel-7402) and breast carcinoma (MCF-7) cells. The results indicated that most compounds exhibited significant antiproliferative activity, in some cases greater than that of cisplatin, and compound 3z was found to be the most potent antiproliferative agent against A549, BGC823, CT-26, Bel-7402 and MCF-7 cell lines with an IC50 value of 2.7 ± 0.4, 2.7 ± 0.6, 2.4 ± 0.2, 3.2 ± 0.2, and 5.6 ± 0.3 μM, respectively. Combined with favorable in vitro potency, the antitumor efficacies of the selected compounds in mice were also evaluated. Compound 3z exhibited potent antitumor activity with a tumor inhibition rate of 48.6% in sarcoma 180 models. Preliminary investigations on the mechanisms of action revealed that compound 3z could dramatically inhibit EA.hy926 cell tube formation in a dose-dependent manner. Further investigation of the preliminary mechanism of action demonstrated that compound 3z had obvious angiogenesis inhibitory effects in the chicken chorioallantoic membrane (CAM) assay. The results of the docking study showed a good fitting of the new compounds 3o and 3z to the active site of VEGFR-2 with a docking score energy of -11.31 kcal per mole and -11.26 kcal per mole, respectively.

Sorafenib-Loaded PLGA-TPGS Nanosystems Enhance Hepatocellular Carcinoma Therapy Through Reversing P-Glycoprotein-Mediated Multidrug Resistance. AAPS PharmSciTech 2022; 23:130. [PMID: 35487999 DOI: 10.1208/s12249-022-02214-y] [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: 11/10/2021] [Accepted: 01/07/2022] [Indexed: 11/30/2022] Open
Abstract
Multidrug resistance (MDR) is a key determinant for hepatocellular carcinoma chemotherapy failure. P-glycoprotein is one of the main causes of MDR by causing drug efflux in tumor cells. In order to solve this thorny problem, we prepared a sorafenib-loaded polylactic acid-glycolic acid (PLGA) - D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) nanoparticles (SPTNs). SPTNs were successfully synthesized through an ultrasonic emulsion solvent evaporation method with a favourable encapsulation efficiency of 90.35%. SPTNs were almost spherical in shape with uniform particle size (215.70 ± 0.36 nm), narrow polydispersity index (0.27 ± 0.02) and negative surface charge (-26.01 ± 0.65 mV). In the cellular uptake assay, the intracellular coumarin-6 (C6) fluorescence of TPGS component-based PLGA nanoparticles (C6-PTNs) was 1.63-fold higher relative to that of PVA component-based PLGA nanoparticles (C6-PVNs). The half-maximal inhibitory concentration and apoptosis ratio of SPTNs against HepG2/MDR cells were 3.90 μM and 75.62%, respectively, which were notably higher than free SF and sorafenib-PLGA-PVA nanoparticles (SPVNs). The anti-drug efflux activities of SPTNs were assessed by the intracellular trafficking assay using verapamil as a P-gp inhibitor. SPTNs could effectively inhibit the drug efflux in tumor cells detected by flow cytometry, and suppressed relative MDR1 gene as well as P-glycoprotein expression in tumor cells. Attributed to the MDR reversion effect of SPTNs, the in vivo antitumor efficacy experiment showed that SPTNs significantly inhibited the tumor growth of HepG2/MDR xenograft-bearing nude mice, and obviously reduced the toxicity against liver and kidney compared with SF treatment. In summary, SPTNs, as highly efficient and safe antitumor nano delivery systems, showed promising potential for hepatocellular carcinoma therapy through reversing P-glycoprotein-mediated MDR.

Abstract
(-)-Homo-renieramycin G and its twenty derivatives were prepared from l-tyrosine methyl ester via a multi-step route. Their cytotoxicities were tested against four human cancer cell lines (A549, HeLa, KB and BGC-823). (-)-Renieramycin G and (-)-homo-renieramycin G showed comparable cytotoxicity against these four cancer cell lines, which indicated that the expansion of ring C from the six-membered 1,4-piperazinone to the seven-membered 1,4-diazepanone had no obvious impact on the cytotoxicity. Compound 42 with methyl side chain and compounds 38-41 with heterocyclic aromatic side chains at C-23 exhibited the most potent cytotoxicity with the IC50 values at the level of 10-6 M.
