Abstract
The synthesis of biphenylmethoxydibenzo[b,f]oxepine or photoswitchable fluorinated dibenzo[b,f]oxepine derivatives with one or three azo bonds, potential microtubule inhibitors, is described. Our studies provide a concise method for constructing derivatives containing the dibenzo[b,f]oxepine skeleton. An analysis of products was run using experimental and theoretical methods. Next, we evaluated the E/Z isomerization of azo-dibenzo[b,f]oxepine derivatives, which could be photochemically controlled using visible-wavelength light.

Gudavalli D, Pandey K, Ede VG, Sable D, Ghagare AS, Kate AS. Phytochemistry and pharmacological activities of five species of Bauhinia genus: A review. Fitoterapia 2024; 174:105830. [PMID: 38286316 DOI: 10.1016/j.fitote.2024.105830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 01/12/2024] [Accepted: 01/23/2024] [Indexed: 01/31/2024]
Abstract
Genus Bauhinia has been widely used in the treatment of diabetes, malaria, cough, headache, fever, piles, dysentery, flatulence, diarrhoea, ulcer and cardiovascular problems. Among 600 species of this genus, Bauhinia variegata, B. purpurea, B. championii, B. racemosa, and B. forficata are commonly used in the traditional medicine and found to be throughly investigated for their medicinal properties. They possess diverse pharmacological activities such as anti-diabetic, anti-microbial, antioxidant, anti-arthritic, cardioprotective, hepatoprotective, nephroprotective, fibrinolytic, and wound healing properties and most of the biological activities are corelating with traditional knowledge. Phytochemical analysis indicated that steroids, terpenoids, and flavonoids are prominent in the selected species, whereas bauhiniastatins, bauhinoxepins, racemosols, roseosides, and bauhichamines are found unique to the genus. This review aims to decipher active molecules from the aforementioned species of Bauhinia covering comprehensive analysis of phytochemistry, pharmacological activities and traditional uses. The data has been carefully analyzed to find compounds or fractions with a translational value. In most of the cases, the pharmacological activities have been established, however, further studies are needed such as safety evaluations, target identification, bioavailability, metabolite identification, and pharmacokinetic properties. In conclusion, the pharmacological potential of Bauhinia plants show promise with various leads such as insulin-like protein, roseoside, bauhiniastatin, and melibiose binding lectin. However, further investigations are required to address existing gaps and advance them towards product development. This review will lay the groundwork for future research initiatives aimed at fully realizing the therapeutic potential of Bauhinia plants.

A New Benzo[6,7]oxepino[3,2-b] Pyridine Derivative Induces Apoptosis in Canine Mammary Cancer Cell Lines. Animals (Basel) 2024; 14:386.

Abstract
CMC is the most frequently diagnosed cancer and one of the leading causes of death in non-spayed female dogs. Exploring novel therapeutic agents is necessary to increase the survival rate of dogs with CMC. MPOBA is a BZOP derivative that has a significant anticancer effect in a human cell line. The main goal of this study was to investigate the anticancer properties of MPOBA against two CMC cell lines (REM134 and CMGT071020) using a 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, a wound healing assay, a transwell migration assay, an Annexin V-FITC apoptosis assay with a flow cytometry analysis, a mRNA expression analysis using quantitative real-time PCR (qRT-PCR), and an immunohistochemistry (IHC). According to the accumulated studies, MPOBA caused significant concentration- and time-dependent reductions in cell proliferation and cell migration and induced apoptosis in both CMC cell lines. In gene expression analysis, nine canine genes, including TP53, BCL-2, BAX, epidermal growth factor receptor (EGFR), snail transcription factor (SNAIL), snail-related zinc-finger transcription factor (SLUG), TWIST, E-cadherin, and N-cadherin, were investigated. The mRNA expression results revealed that MPOBA induced upregulation of TP53 and overexpression of the pro-apoptotic gene BAX, together with an inhibition of BCL-2. Moreover, MPOBA also suppressed the mRNA expression levels of SNAIL, EGFR, and N-cadherin and induced upregulation of E-cadherin, crucial genes related to the epithelial-to-mesenchymal transition (EMT). However, there was no significant difference in the IHC results of the expression patterns of vimentin (VT) and cytokeratin (CK) between MPOBA-treated and control CMC cells. In conclusion, the results of the present study suggested that MPOBA exhibited significant anticancer activity by inducing apoptosis in both CMCs via upregulation of TP53 and BAX and downregulation of BCL-2 relative mRNA expression. MPOBA may prove to be a potential candidate drug to be further investigated as a therapeutic agent for CMC.

Abstract
In this work, we report a novel and simple one-pot synthesis of substituted dibenzo[b,f]oxepines under transition-metal-free conditions. This cascade process involves nucleophilic aromatic substitution followed by Knoevanagel condensation, as evidenced by the isolated reaction intermediates. We have also achieved the synthesis of anticancer bauhinoxepin C in 7 steps with 5.1% overall yield using this synthetic approach.

Abstract
In this report, we have described a FeCl3-catalyzed process involving intramolecular annulation of o-phenoxy diarylacetylenes via hydroarylation to afford a series of biologically potent fused seven-membered (6-7-6) ring compounds under mild reaction conditions. This reaction was believed to proceed through Friedel-Crafts type sequential carbometallation followed by protonation to produce phenyldibenz[b,f]oxepines. This method was also extended to synthesize seven-membered rings that are fused with coumarins.
