Abstract
An organoselenium-catalyzed C2,3-diarylation of unprotected N-H indoles with electron-rich aromatics has been developed. This one-pot multicomponent tandem cross-dehydrogenation coupling reaction allows for the incorporation of two different aromatic groups to indoles. More importantly, this approach offers significant advantages, including a high atom and step economy, eliminating the need for prepreparation of the reaction substrates, streamlining the synthetic process and enhancing its practicality. Overall, this organoselenium-catalyzed C2,3-diarylation reaction presents an efficient and versatile strategy for the functionalization of indole derivatives.

Anthraquinones from the roots of Morinda scabrida Craib exhibit antiproliferative activity against A549 lung cancer cells and antitubulin polymerization. Fitoterapia 2024; 173:105781.

Abstract
Six anthraquinones were isolated from Morinda scabrida Craib, an unexplored species of Morinda found in the tropical forest of Thailand. All six anthraquinones showed cytotoxicity against A549 lung cancer cells, with the most active compound, nordamnacanthal (MS01), exhibiting the IC50 value of 16.3 ± 2.5 μM. The cytotoxic effect was dose-dependent and led to cell morphological changes characteristic of apoptosis. In addition, flow cytometric analysis showed dose-dependent apoptosis induction and the G2/M phase cell cycle arrest, which was in agreement with the tubulin polymerization inhibitory activity of MS01. Molecular docking analysis illustrated the binding between MS01 and the α/β-tubulin heterodimer at the colchicine binding site, and UV-visible absorption spectroscopy revealed the DNA binding capacity of MS01.

Abstract
Microtubules are appealing as intracellular targets for anticancer activity due to their importance in cell division. Three important binding sites are present on the tubulin protein: taxane, vinca, and colchicine binding sites (CBS). Many USFDA-approved drugs such as paclitaxel, ixabepilone, vinblastine, and combretastatin act by altering the dynamics of the microtubules. Additionally, a large number of compounds have been synthesized by medicinal chemists around the globe that target different tubulin binding sites. Although CBS inhibitors have proved their cytotoxic potential, no CBS-targeting drug had been able to reach the market. Several studies have reported design, synthesis, and biological evaluation of indole derivatives as potential anticancer agents. These compounds have been shown to inhibit cancer cell proliferation, induce apoptosis, and disrupt microtubule formation. Moreover, the binding affinity of these compounds to the CBS has been demonstrated using molecular docking studies and competitive binding assays. The present work has reviewed indole derivatives as potential colchicine-binding site inhibitors. The structure-activity relationship studies have revealed the crucial pharmacophoric features required for the potent and selective binding of indole derivatives to the CBS. The development of these compounds with improved efficacy and reduced toxicity could potentially lead to the development of novel and effective cancer therapies.

Abstract
A transition metal-free multicomponent reaction using lithiated indole, boronic ester, pyridine, and ethyl chloroformate was developed to access C2,C3 bis-arylated indoles, which are present in several marketed drugs and bioactive compounds. One-pot access to unsymmetrical C2,C3-diaryl indole from the parent indole remains a huge synthetic challenge. Our group was able to achieve this goal through a transition metal-free 1,2-metalate rearrangement of the indole boronate complex. The reaction of indole boronate species with activated pyridine allows 1,2-migration to access pyridyl-indoleboronate species, which will convert to the corresponding indole upon oxidation and indoline after deborylation. The reaction tolerates substituted pyridines, quinolone, isoquinoline, and more. Both aryl and alkyl boronic esters were accommodated under optimized reaction conditions. Apart from mechanistic studies using 11B-NMR, this methodology has been applied to the gram-scale synthesis of several bioactive compounds.

Abstract
Five mono-tetrahydrofuran acetogenins: uvamicranins A-E and three known mono-tetrahydrofuran acetogenins; reticulatacin, calamistrin A, and uvarigrin, were isolated from the stems of Uvaria micrantha (Annonaceae). Their structures were elucidated by 2D NMR and high-resolution mass spectral analysis. The absolute configurations of uvamicranins A and B were determined by modified Mosher's method. Evaluation of antiproliferative activity of the isolated compounds showed that they were more potent towards the human hepatocellular carcinoma cell line HepG2, compared to the five other tested cell lines. Among the tested compounds, uvamicranin B (UvB) and uvarigrin (Uv) possessed strong antiproliferative activity with IC50 values of 2.89 ± 0.71 μM and 0.37 ± 0.06 μM, respectively. The antiproliferative mechanism of UvB and Uv, was investigated in HepG2 cell line showing that both compounds marginally induced apoptotic cell death, but exhibited cytostatic effect through induction of cell cycle arrest at the G2/M phase.

Abstract
A collection of 2,3-arylpyridylindole derivatives were synthesized via the Larock heteroannulation and evaluated for their in vitro cytotoxic activity against A549 human lung cancer cells. Two derivatives expressed good cytotoxicity with IC 50 values of 1.18±0.25 μM and 0.87±0.10 μM and inhibited tubulin polymerization in vitro , with molecular docking studies suggesting the binding modes of the compounds in the colchicine binding site. Both derivatives have biphasic cell cycle arrest effects depending on their concentrations. At a lower concentration (0.5 μM), the two compounds induced G0/G1 cell cycle arrest by activating the JNK/p53/p21 pathway. At a higher concentration (2.0 μM), the two derivatives arrested the cell cycle at the G2/M phase via Akt signaling and inhibition of tubulin polymerization. Additional cytotoxic mechanisms of the two compounds involved the decreased expression of Bcl-2 and Mcl-1 antiapoptotic proteins through inhibition of the STAT3 and Akt signaling pathways.

Abstract
Tubulin inhibitors can interfere with normal cell mitosis and inhibit cell proliferation through interfering with the normal structure and function of microtubules, forming spindle filaments. Indole, as a privileged pharmacological skeleton, has been widely used in anti-cancer inhibitors. A variety of alkaloids containing an indole core obtained from natural sources have been proven to inhibit tubulin polymerization, and an ever-increasing number of synthetic indole-based tubulin inhibitors have been reported. Among these, several kinds of indole-based derivatives, such as TMP analogues, aroylindoles, arylthioindoles, fused indole, carbazoles, azacarbolines, alkaloid nortopsentin analogues and bis-indole derivatives, have shown good inhibition activities towards tubulin polymerization. The binding modes and SARs investigations of synthetic indole derivatives, along with a brief mechanism on their anti-tubulin activity, are presented in this review.

Abstract
Due to drug resistance and disease recurrence, lung cancer remains one of the primary cancer-related causes of death in both men and women worldwide. In addition, lung cancer is clinically silent and thus most patients are at an advanced stage at the time of diagnosis. The limited efficiency of current conventional chemotherapies necessitates the search for novel effective anticancer agents. The present study demonstrated the anti-proliferative effect and apoptosis-inducing activity of three sesquiterpene lactones isolated from Gymnanthemum extensum, vernodalin (VDa), vernolepin (VLe) and vernolide (VLi), on A549 human lung cancer cells. Treatment with sub-cytotoxic doses (cell viability remaining >75%) of VDa, VLe and VLi, arrested progression of the A549 cell cycle at the G0/G1 phase, while cytotoxic doses of the three compounds induced G2/M phase arrest and apoptosis. Mechanistic studies revealed that VDa, VLe and VLi may exert their anti-tumor activity through the JAK2/STAT3 pathway. Molecular docking analysis confirmed that VDa, VLe and VLi formed hydrogen bonds with the FERM domain of JAK2 protein. Overall, the present study highlighted the potential therapeutic value of VDa, VLe and VLi to be further developed as anticancer agents for the treatment of lung cancer.

Abstract
Selenium is important to human health, particularly for immune response and cancer prevention. Chitosan has good biocompatibility and low toxicity. In this paper, we synthesized chitosan selenate (CS), a novel therapeutic compound, using chitosan and selenium. CS synthesis was evaluated using FTIR, which verified the presence of a characteristic SeO absorption peak at 892 cm-1, and with HPGPC, which calculated the molecular weight as approximately 41.8 kDa. Next, we evaluated the proliferation-inhibitory and apoptosis-inducing effects of CS on lung cancer A549 cells and explored its potential molecular mechanisms. MTT assay indicated that CS could significantly inhibit A549 cells viability in a dose-dependent manner. Typical morphological features of apoptosis were observed by Hoechst staining in A549 cells treated with CS, and Annexin V-FITC/PI staining confirmed that CS induced cell death via apoptosis and not necrosis. Cell cycle detection showed that CS triggered S and G2/M phase arrest in a dose-dependent manner. Finally, western blot analysis indicated that CS up-regulated the expression levels of Fas, FasL, and Fadd; subsequently, activated the caspase cascade in A549 cells. These results show that CS induces apoptosis in A549 cells via the Fas/FasL signaling pathway, and has potential chemopreventive effects for lung cancer treatment.

Abstract
A convenient, metal-free, and organic acid-base promoted synthetic method to prepare 3-arylindoles from 3-aryloxirane-2-carbonitriles and arylhydrazine hydrochlorides has been developed. In the reaction, the organic acid catalyzes a tandem nucleophilic ring-opening reaction of aryloxiranecarbonitriles and arylhydrazine hydrochlorides and Fischer indolization. The organic base triethylamine plays a crucial role in the final elimination step in the Fischer indole synthesis, affording 3-arylindoles regiospecifically. The reaction features advantages of microwave acceleration, non-metal participation, short reaction time, organic acid-base co-catalysis, and broad substrate scope.

Overcoming the diverse mechanisms of multidrug resistance in lung cancer cells by photodynamic therapy using pTHPP-loaded PLGA-lipid hybrid nanoparticles. Eur J Pharm Biopharm 2020; 149:218-228.

Abstract
Multidrug resistance (MDR) and the spread of cancer cells (metastasis) are major causes leading to failure of cancer treatment. MDR can develop in two main ways, with differences in their mechanisms for drug resistance, first drug-selected MDR developing after chemotherapeutic treatment, and metastasis-associated MDR acquired by cellular adaptation to microenvironmental changes during metastasis. This study aims to use a nanoparticle-mediated photodynamic therapy (NPs/PDT) approach to overcome both types of MDR. A photosensitizer, 5,10,15,20-Tetrakis(4-hydroxy-phenyl)-21H,23H-porphine (pTHPP) was loaded into poly(D,L-lactide-co-glycolide) (PLGA)-lipid hybrid nanoparticles. The photocytotoxic effect of the nanoparticles was evaluated using two different MDR models established from one cell line, A549 human lung adenocarcinoma, including (1) A549RT-eto, a MDR cell line derived from A549 cells by drug-selection, and (2) detachment-induced MDR acquired by A549 cells when cultured as floating cells under non-adherent conditions, which mimic metastasizing cancer cells in the blood/lymphatic circulation. In the drug-selected MDR model, A549RT-eto cells displayed 17.4- and 1.8-fold resistance to Etoposide and Paclitaxel, respectively, compared to the A549 parental cells. In contrast to treatment with anticancer drugs, NPs/PDT with pTHPP-loaded nanoparticles resulted in equal photocytotoxic effect in A549RT-eto and parental cells. Intracellular pTHPP accumulation and light-induced superoxide anion generation were observed at similar levels in the two cell lines. The NPs/PDT killed A549RT-eto and parental cells through apoptosis as revealed by flow cytometry. In the metastasis-associated MDR model, A549 floating cells exhibited resistance to Etoposide (11.6-fold) and Paclitaxel (57.8-fold) compared to A549 attached cells, but the floating cells failed to show resistance against the photocytotoxic effect of the NPs/PDT. The MDR overcoming activity of NPs/PDT is mainly due to delivery ability of the PLGA-lipid hybrid nanoparticles. In conclusion, this work suggests that PLGA-lipid hybrid nanoparticles have potential in delivering photosensitizer or chemotherapeutic drug for treating both drug-selected and metastasis-associated MDR lung cancer cells.

Abstract
Vernonia extensa, known as "Phim Phai Lin" in Thai, is distributed in most regions of Thailand. The plant has been used in Ayurveda and traditionally used to treat malaria and cancer, and possesses several sesquiterpene lactones. This study aimed to investigate and identify the active constituents by bioactivity-based analysis, as well as to evaluate the cytotoxic activity of V. extensa by MTT or XTT assays in ten cancer cell lines (Liver HepG2 and S102; Bile duct HuCCA-1; Leukemia HL-60 and MOLT-3; Lung A549 and H69AR; Breast MDA-MB-231 and T47D; Cervical HeLa). Bioactivity-guided fractionation and semi-preparative HPLC purification were used to separate the bioactive constituents. Apoptosis-inducing activity and cell cycle inhibitory effect of selected active compounds were determined on HepG2 cells by flow cytometric analysis. Bioactivity-guided fractionation of the CH2Cl2 extract and chemical investigation of the cytotoxic fractions led to the isolation of a new sesquiterpenoid pseudo-dimer named vernodalidimer L, together with eight known sesquiterpenoids from the aerial part of V. extensa. The structures of the isolates were elucidated based on spectroscopic analysis, including 1D and 2D NMR and HRMS. Vernolide has potent broad-spectrum cytotoxicity with IC50 values in the range of 0.91-13.84 μM, against all ten cancer cell lines. The annexin-V flow cytometric analysis showed that vernodalin, vernolepin, and vernolide induced apoptosis on HepG2 cells in a dose dependent manner and these effects correlated with G2/M phase cell cycle arrest. Our results indicated that vernodalin, vernolepin, and vernolide have potential to be used as lead compounds in the development of a therapeutic natural product for treatment of liver cancer.

Abstract
Seleno-short-chain chitosan (SSCC) is a synthesized chitosan derivative. In this study, antitumor activity and underlying mechanism of SSCC on human non-small-cell lung cancer A549 cells were investigated in vitro. The MTT assay showed that SSCC could inhibit cell viability in a dose- and time-dependent manner, and 200 μg/ml SSCC exhibited significantly toxic effects on A549 cells. The cell cycle assay showed that SSCC triggered S phase cell cycle arrest in a dose- and time-dependent manner, which was related to a downregulation of S phase associated cyclin A. The DAPI staining and Annexin V-FITC/PI double staining identified that the SSCC could induce A549 cells apoptosis. Further studies found that SSCC led to the generation of reactive oxygen species (ROS) and the disruption of mitochondrial membrane potential (MMP) by DCFH-DA and Rhodamin 123 staining, respectively. Meanwhile, free radical scavengers N-acetyl-L-cysteine (NAC) pretreatment confirmed that SSCC-induced A549 cells apoptosis was associated with ROS generation. Furthermore, real-time PCR and western blot assay showed that SSCC up-regulated Bax and down-regulated Bcl-2, subsequently incited the release of cytochrome c from mitochondria to cytoplasm, activated the increase of cleaved-caspase 3 and finally induced A549 cells apoptosis in vitro. In general, the present study demonstrated that SSCC induced A549 cells apoptosis via ROS-mediated mitochondrial apoptosis pathway.
