Design, synthesis, and biological evaluation of potent 1,2,3,4-tetrahydroisoquinoline derivatives as anticancer agents targeting NF-κB signaling pathway. Bioorg Med Chem 2021; 46:116371. [PMID: 34500188 DOI: 10.1016/j.bmc.2021.116371] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/09/2021] [Accepted: 08/11/2021] [Indexed: 12/20/2022]
Abstract
The multifunctional transcription factor, nuclear factor-κB (NF-κB), is broadly involved in multiple human diseases, such as cancer and chronic inflammation, through abnormal modulations of the NF-κB signaling cascades. In patients with several types of cancer diseases, NF-κB is excessively activated, which could result in the stimulation of proliferation and/or suppression of apoptosis. Herein, we present a new series of 1,2,3,4-tetrahydroisoquinoline derivatives with good anticancer activities against various human cancer cell lines, which are rationally designed based on our novel NF-κB inhibitors. The SAR studies demonstrated that compound 5d with a methoxy group at the R3 position exhibits the most anti-proliferative activity with GI50 values, ranging 1.591 to 2.281 μM. Similar to KL-1156, the compound 5d (HSR1304) blocked NF-κB nuclear translocation step in LPS-stimulated MDA-MB-231 cells, probably leading to cytotoxic potency against tumor cells. Together with known potent NF-κB inhibitors containing diverse core heterocyclic moieties, the 1,2,3,4-tetrahydroisoquinoline derivatives can provide structural diversity, enhancing a potential for the development of a novel class of anticancer drugs.

Design and synthesis of 2,3-dihydro- and 5-chloro-2,3-dihydro-naphtho-[1,2-b]furan-2-carboxylic acid N-(substitutedphenyl)amide analogs and their biological activities as inhibitors of NF-κB activity and anticancer agents. Arch Pharm Res 2016; 39:618-30.

Abstract
A series of 2,3-dihydro- and 5-chloro-2,3-dihydro-naphtho-[1,2-b]furan-2-carboxylic acid N-(substitutedphenyl)amide analogs (1a-k and 2a-i) were designed and synthesized for developing novel naphthofuran scaffolds as anticancer agents and inhibitors of NF-κB activity. Compound 1d, which had a 4'-chloro group on the N-phenyl ring, exhibited inhibitory activity of NF-κB. Compound 2g, which had a 5'-chloro group on the naphthofuran ring and a 3',5'-bistrifluoromethane group on the N-phenyl ring, had the best NF-κB inhibitory activity. In addition, the novel analogs exhibited potent cytotoxicity at low concentrations against HCT-116, NCI-H23, and PC-3 cell lines. The two electron-withdrawing groups, especially at the 3',5'-position on the N-phenyl ring, increased anticancer activity and NF-κB inhibitory activity. However, only 5-chloro-2,3-dihydronaphtho[1,2-b]furan-2-carboxylic N-(3',5'-bis(trifluoromethyl)phenyl)amide (2g) exhibited both outstanding cytotoxicity and NF-κB inhibitory activities. This novel lead scaffold may be helpful for investigation of new anticancer agents by inactivation of NF-κB.

A novel synthetic compound MCAP suppresses LPS-induced murine microglial activation in vitro via inhibiting NF-kB and p38 MAPK pathways. Acta Pharmacol Sin 2016; 37:334-43.

Abstract
AIM To investigate the anti-neuroinflammatory activity of a novel synthetic compound, 7-methylchroman-2-carboxylic acid N-(2-trifluoromethyl) phenylamide (MCAP) against LPS-induced microglial activation in vitro. METHODS Primary mouse microglia and BV2 microglia cells were exposed to LPS (50 or 100 ng/mL). The expression of iNOS and COX-2, proinflammatory cytokines, NF-κB and p38 MAPK signaling molecules were analyzed by RT-PCR, Western blot and ELISA. The morphological changes of microglia and nuclear translocation of NF-ĸB were visualized using phase contrast and fluorescence microscopy, respectively. RESULTS Pretreatment with MCAP (0.1, 1, 10 μmol/L) dose-dependently inhibited LPS-induced expression of iNOS and COX-2 in BV2 microglia cells. Similar results were obtained in primary microglia pretreated with MCAP (0.1, 0.5 μmol/L). MCAP dose-dependently abated LPS-induced release of TNF-α, IL-6 and IL-1β, and mitigated LPS-induced activation of NF-κB by reducing the phosphorylation of IκBα in BV2 microglia cells. Moreover, MCAP attenuated LPS-induced phosphorylation of p38 MAPK, whereas SB203580, a p38 MAPK inhibitor, significantly potentiated MCAP-caused inhibition on the expression of MEF-2 (a transcription factor downstream of p38 MAPK). CONCLUSION MCAP exerts anti-inflammatory effects in murine microglia in vitro by inhibiting the p38 MAPK and NF-κB signaling pathways and proinflammatory responses. MCAP may be developed as a novel agent for treating diseases involving activated microglial cells.

Abstract
A novel class of NF-κB inhibitors were designed and synthesized based on KL-1156 (6-hydroxy-7-methoxychroman-2-carboxylic acid phenyl amide) which is unambiguously considered to be a promising inhibitor for the translocation step of NF-κB. Especially in this study we focused on the modifying the chroman moiety of KL-1156 into four parts for exploring the SAR studies linked with physical properties of substituents resulted the development of novel 1a-k, 2a-f, 3a-d and 4a-d derivatives of 3,4-dihydro-2H-benzo[h]chromene. From the SAR studies we were very delightfully identified that several new N-aryl-3,4-dihydro-2H-benzo[h]chromene-2-carboxamide derivatives (1a-k) exhibited good inhibitory activity and anti-proliferative activity than parent lead compound KL-1156, among them 1i exhibited outstanding inhibitory effect on LPS-induced NF-κB transcriptional activity and anti-proliferative activity on NCI-H23 lung cancer cell lines than KL-1156.

Abstract
We report a novel Lewis acid catalysed tandem reaction of isocyanides, chromone 3-carboxylic acid and nucleophiles. An experimentally very simple procedure, involving the use of microwave irradiation in the presence of a Lewis acid catalyst, affords a representative collection of chromone-2-carboxamides and chromone-2-carboxamido-3-esters in high yields, in just a few minutes. Such an unprecedented strategy is formally equivalent to a conjugate addition of isocyanides to Michael acceptors.
