Moderately lipophilic 2-(Het)aryl-6-dithioacetals, 2-phenyl-1,4-benzodioxane-6-dithioacetals and 2-phenylbenzofuran-5-dithioacetals: Synthesis and primary evaluation as potential antidiabetic AMPK-activators. Bioorg Med Chem 2023; 87:117303. [PMID: 37167713 DOI: 10.1016/j.bmc.2023.117303] [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: 03/06/2023] [Revised: 04/24/2023] [Accepted: 04/26/2023] [Indexed: 05/13/2023]
Abstract
Since the 1950's, AMP-kinase (AMPK) has been used as a promising target for the development of antidiabetic drugs against Type 2 diabetes mellitus (T2D). Indeed, the canonical antidiabetic drug metformin recruits, at least partially, AMPK activation for its therapeutic effect. Herein we present design and synthesis of 20 novel relatively polar cyclic and acyclic dithioacetals of 2-(Het)arylchroman-6-carbaldehydes, 2-phenyl-1,4-benzodioxane-6-carbaldehyde, and 2-phenylbenzofuran-5-carbaldehyde, which were developed as potential AMPK activators. Three of the synthesized dithioacetals demonstrated significant enhancement (≥70%) of glucose uptake in rat L6 myotubes. Noteworthy, one of the dithioacetals, namely 4-(6-(1,3-dithian-2-yl)chroman-2-yl)pyridine, exhibited high potency comparing to other molecules. It increased the rate of glucose uptake in rat L6 myotubes and augmented insulin secretion from rat INS-1E cells in pharmacological relevant concentrations (up to 2 μM). Both effects were mediated by activation of AMPK. In addition, the compound showed excellent pharmacokinetic profile in healthy mice, including maximal oral bioavailability. Such bifunctionality (increased glucose uptake and insulin secretion) can be used as a starting point for the development of a novel class of antidiabetic drugs with dual activity that is relevant for T2D treatment.

One pot tandem dehydrogenative cross-coupling of primary and secondary alcohols by ruthenium amido-functionalized 1,2,4-triazole derived N-heterocyclic carbene complexes. RSC Adv 2022; 12:28961-28984. [PMID: 36320780 PMCID: PMC9557752 DOI: 10.1039/d2ra05531g] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 09/29/2022] [Indexed: 11/05/2022] Open
Abstract
One-pot tandem dehydrogenative cross-coupling of primary and secondary alcohols was catalyzed by three ruthenium complexes [1-(R)-4-N-(furan-2-ylmethyl)acetamido-1,2,4-triazol-5-ylidene]Ru(p-cymene)Cl [R = Et (1b), i-Pr (2b), Bn (3b)], of amido-functionalized 1,2,4-triazole derived N-heterocyclic carbene (NHC) ligands. Density Functional Theory (DFT) calculations were employed for the ruthenium (1b) precatalyst to understand this reaction mechanism completely, and the mechanisms adapted are divided categorically into three steps (i) nucleophilic substitution of chloride ions by alcohols, (ii) dehydrogenation of primary and secondary alcohols, and (iii) olefin and ketone hydrogenation. Our mechanistic study reveals that the formation of a deprotonated Ru-alcoholate (A) or (E) intermediate is favorable compared to the protonated form (A') or (E') from (1b) by associative nucleophilic substitution. Though an ionic pathway that proceeds through (A') or (E'), has less barriers in the dehydrogenation and olefin/ketone hydrogenation steps than that of the neutral pathway, proceeding through (A) or (E), a steep energy barrier was observed in the first nucleophilic substitution step, prohibiting the reaction to proceed via the intermediate (A') or (E'). Thus, our thorough mechanistic study reveals that the reaction proceeds via deprotonated Ru-alcoholate (A) or (E) species. Furthermore, the 1,4 addition of an α,β-unsaturated carbonyl compound is kinetically and thermodynamically favorable over the 1,2 addition, and the experiments support these observations. As a testimony towards practical application in synthesizing bio-active flavonoid based natural products, five different flavan derivatives (16-20), were synthesized by the dehydrogenative coupling reaction using the neutral ruthenium (1-3)b complexes.

Betulinic Acid and Brosimine B Hybrid Derivatives as Potential Agents against Female Cancers. Anticancer Agents Med Chem 2020; 20:622-633. [DOI: 10.2174/1871520620666200124111634] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 07/24/2019] [Accepted: 08/16/2019] [Indexed: 12/22/2022]
Abstract
Background:
Cancer is a multifactorial disease, representing one of the leading causes of death
worldwide. On a global estimate, breast cancer is the most frequently occurring cancer in women and cervical
cancer, the fourth most common. Both types of cancer remain the major cause of cancer-related mortality in
developing countries. A strategy for rational drug design is hybridization, which aims to bring together in one
molecule, two or more pharmacophores in order to reach several biological targets.
Objective:
The objective of this work was to develop new hybrids based on natural pharmacophores: Betulinic
acid (1) and brosimine b (2), active in female cancer cell lines.
Methods:
The coupling reactions were carried out by Steglich esterification. Different compounds were designed
for the complete and simplified structural hybridization of molecules. The anticancer activities of the
compounds were evaluated in human cervical adenocarcinoma (HeLa), human cervical metastatic epidermoid
carcinoma (ME-180), and human breast adenocarcinoma (MCF-7) cell lines.
Results:
Hybrid 3 presented higher potency (IC50 = 9.2 ± 0.5μM) and SI (43.5) selectively in MCF-7 cells (in
relation to Vero cells) with its cytotoxic effect occurring via apoptosis. In addition, compound 6 showed activity
in MCF-7 and HeLa cells with intermediate potency, but with high efficacy, acting via apoptosis as well.
Conclusion:
In this context, we showed that the combination of two complex structures generated the development
of hybrids with differing inhibitory profiles and apoptotic modes of action, thus representing potential
alternatives in female cancer treatment.

Abstract
Chalcone, a privileged structure, is considered as an effective template in the field of medicinal chemistry for potent drug discovery. In the present study, a privileged template chalcone was designed, synthesized, and characterized by various spectroscopic techniques (NMR, high-resolution mass spectrometry, Fourier transform infrared (FT-IR) spectroscopy, UV spectroscopy, and single-crystal X-ray diffraction). The mechanism of binding of chalcone with bovine serum albumin (BSA) was determined by multispectroscopic techniques and computational methods. Steady-state fluorescence spectroscopy suggests that the intrinsic fluorescence of BSA was quenched upon the addition of chalcone by the combined dynamic and static quenching mechanism. Time-resolved spectroscopy confirms complex formation. FT-IR and circular dichroism spectroscopy suggested the presence of chalcone in the BSA molecule microenvironment and also the possibility of rearrangement of the native structure of BSA. Moreover, molecular docking studies confirm the moderate binding of chalcone with BSA and the molecular dynamics simulation analysis shows the stability of the BSA-drug complex system with minimal deformability fluctuations and potential interaction by the covariance matrix. Moreover, pharmacodynamics and pharmacological analysis show good results through Lipinski rules, with no toxicity profile and high gastrointestinal absorptions by boiled egg permeation assays. This study elucidates the mechanistic profile of the privileged chalcone scaffold to be used in therapeutic applications.

Abstract
BACKGROUND Aggregation of misfolded amyloid β (Aβ) in senile plaques causes oxidative stress and neuronal death in Alzheimer's disease (AD). Compounds possessing antiaggregation and antioxidant properties are promising candidate compounds for AD treatment. METHODS We examined the potential of synthetic derivatives of licochalcone A and coumarin for inhibiting Aβ aggregation, scavenging reactive oxygen species (ROS), and providing neuroprotection by using biochemical assays and Tet-On Aβ-GFP 293/SH-SY5Y cell models for AD. RESULTS Among test compounds, LM-031, a novel chalcone-coumarin hybrid, inhibited Aβ aggregation and scavenged free oxygen radicals. LM-031 markedly reduced Aβ misfolding and ROS as well as promoted neurite outgrowth and inhibited acetylcholinesterase in Tet-On Aβ-GFP 293/SH-SY5Y cells. Mechanistic studies showed upregulation of the HSPB1 chaperone, NRF2/NQO1/GCLC pathway, and CREB/BDNF/BCL2 pathway. Decreased neurite outgrowth upon the induction of Aβ-GFP was rescued by LM-031, which was counteracted by knockdown of HSPB1, NRF2, or CREB. CONCLUSION Taken together, these findings demonstrate that LM-031 exhibited antiaggregation, antioxidant, and neuroprotective effects against Aβ toxicity by enhancing HSPB1 and the NRF2-related antioxidant pathway as well as by activating the CREB-dependent survival and antiapoptosis pathway. These results imply that LM-031 may be a new therapeutic compound for AD.

Abstract
An efficient synthesis of novel functionalized 2-aryl-4-(indol-3-yl)-4H-chromenes has been developed, in the presence of a catalytic amount of iodine, from easily available starting materials, 2-hydroxychalcone derivatives. Indole, substituted indoles and 7-azaindole are suitable for this transformation. The possible domino Michael addition-intramolecular cyclization reaction mechanism is proposed.
