[PMID: 38516597 PMCID: PMC10953481 DOI: 10.1039/d3md00665d] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 02/06/2024] [Indexed: 03/23/2024] Open
Abstract
A new library of allo-gibberic acid-based aminoalcohol regioisomers was synthesised stereoselectively starting from commercially available gibberellic acid, which yields allo-gibberic acid under mild acidic conditions. The successful formation of hydroxymethyl ketone derivative 5, by acid-mediated rearrangement of previously prepared epoxide, paved the way to obtain the desired 1,3-aminoalcohols through Schiff base formation. To obtain the desired regioisomers, the primary alcohol functionality of 5 was subjected to mesylation, then replaced with either primary amine or sodium azide. The formed azide derivative was subjected to either CuAAC reaction to obtain 1,2,3-triazoles or underwent Pd-catalysed hydrogenolysis to obtain primary aminoalcohol, which was further transformed into 1,3-aminoalcohols by reductive alkylation. All prepared aminoalcohols were identified in a satisfactory manner using modern spectroscopic techniques and assessed for their antiproliferative activity against a panel of human cancer cell lines. The antiproliferative effects of the prepared compounds were assayed by in vitro MTT method against a panel of human cancer cell lines (HeLa, SiHa, A2780, MCF-7 and MDA-MB-231). A significant difference was observed in the antiproliferative activity between the regioisomers. Some compounds exerted outstanding activities against the malignant cells with limited action on fibroblasts, indicating considerable cancer selectivity.

Abstract
A BF3-mediated domino dehydration/electrophilic cyclization of silylalkynols to form 2,3-fused tricyclic benzofulvenes was achieved. In the latter step, in situ generated BF3·OH2 enables the electrophilic activation of alkynes. The predominant Z-selectivity of the reaction is also discussed.

Abstract
A new colchinoid compound, identified as N-deacetyl-N-formylcornigerine (1), named glorigerine was isolated from the roots of Gloriosa superba, along with two known compounds. The structures of isolated compounds were elucidated by 1 D and 2 D NMR and HRMS experiments. Glorigerine (1) differed from cornigerine (6) by the presence of an N-formyl group instead of the N-acetyl group. Glorigerine (1) was found to have moderate cytotoxicity when tested against four human cancer cell lines.

Abstract
A fast and efficient method for synthesising ipomone (4), a bicyclo[3.2.1]octanone containing aromatised derivative, from gibberellic acid (1) has been developed using molecular iodine as a mild and effective mediator under heating conditions in a single step. Evidence was obtained that the reaction simultaneously proceeds through aromatisation and pinacol-pinacolone type 1,2-alkyl shift. Use of excess iodine afforded iodomethyl derivative (5) that could serve as starting material for the synthesis of additional analogs.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 314:116634. [PMID: 37178984 DOI: 10.1016/j.jep.2023.116634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 04/17/2023] [Accepted: 05/11/2023] [Indexed: 05/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pharbitidis Semen (the seeds of Ipomoea nil (L.) Roth or Ipomoea purpurea (L.) Roth), a popular traditional Chinese medicine, is also known as "Heichou" or "Baichou" (Chinese: , ). It can purge the bowels, promote diuresis, remove stagnated accumulation, and kill worms. It can be used for treating anasarca with constipation and oliguria; dyspnea and cough caused by retained fluid; abdominal pain because of intestinal parasitosis; ascariasis; and taeniasis. AIMS This review discusses the botany, ethnopharmacology, phytochemistry, pharmacological activities, toxicology, and quality control of Pharbitidis Semen, to obtain a complete understanding of its effects and provide a basis for further research and the development of new drugs. MATERIALS AND METHODS The literature on Pharbitidis Semen is mainly obtained from pharmacopoeias of different countries, masterpieces of traditional Chinese medicine, Master's and Ph.D. theses, and published articles obtained from literature retrieval websites, such as CNKI, PubMed, SciFinder, WanFang data, Web of Science, Springer, ScienceDirect, Wiley, ACS Publications, Taylor & Francis, J-STAGE, and Google Scholar. Its botany, ethnopharmacology, phytochemistry, pharmacological activities, toxicology, and quality control are discussed to understand its effects and provide a basis for further research. RESULTS Pharbitidis semen has been used ethnomedically in many tropical and subtropical countries as deobstruents, diuretics, and anthelmintics. About 170 chemical compounds, including terpenoids, phenylpropanoids, resin glycosides, fatty acids and other compounds, have been isolated. It has been reported to have different effects, including laxative, renal-protective, neuroprotective, insecticidal, antitumor, anti-inflammatory, and antioxidant. Moreover, a brief introduction to processing, toxicity, and quality control is provided. CONCLUSIONS The traditional efficacy of Pharbitidis Semen in diarrhea has been confirmed, but its bioactive and toxic ingredients are not entirely clear. It is necessary to strengthen the research and identification of effective parts or natural active components of Pharbitidis Semen, clarify the molecular mechanism of its toxicity and change rule of endogenous substances to make Pharbitidis Semen better used in clinical practice. Additionally, the imperfect quality standard is also a challenge that must be solved urgently. The study of modern pharmacology has broadened the application of Pharbitidis Semen and provided ideas for better utilization of this resource.

Abstract
Gloriosine, a colchicine-like natural product, is widely obtained from Gloriosa superba roots. Despite having remarkable anticancer potential, colchicine could not pave its way to the clinic, while gloriosine is yet to be investigated for its pharmacological effects. In the present work, 14 compounds, including gloriosine, were isolated from the G. superba roots and were characterized by NMR spectroscopy. Gloriosine (11) was evaluated for its antiproliferative activity against a panel of 15 human cancer cell lines of different tissues and normal breast cells. Gloroisine (11) displayed significant antiproliferative activity against various cancer cell lines selectively, with IC50 values ranging from 32.61 to 100.28 nM. Further, gloriosine (11) was investigated for its apoptosis-inducing ability and found to form apoptotic bodies. It also inhibited A549 cell migration in the wound healing assay. Finally, molecular docking studies were performed to explore the possible binding modes of gloriosine with the colchicine-binding site of tubulin protein. Our findings suggested that gloriosine might be a potential lead for anticancer drug discovery.
