Design, Synthesis and Evaluations of New 10‐Triazolyl‐1‐methoxygenipin Analogues for Their Cytotoxicity to Cancer Cells

Genipin Analogue (G300) Inhibits Adipogenic Differentiation of Human Bone Marrow-Derived Mesenchymal Stem Cells through the Suppression of Adipogenic Promoting Factors

While obesity is a well-known health threatening condition worldwide, effective pharmacological interventions for obesity suppression have been limited due to adverse effects. Therefore, it is important to explore alternative medical treatments for combating obesity. Inhibition of the adipogenesis process and lipid accumulation are critical targets for controlling and treating obesity. Gardenia jasminoides Ellis is a traditional herbal remedy for various ailments. A natural product from its fruit, genipin, has major pharmacological properties; it is anti-inflammatory and antidiabetic. We investigated the effects of a genipin analogue, G300, on adipogenic differentiation in human bone marrow mesenchymal stem cells (hBM-MSCs). G300 suppressed the expression of adipogenic marker genes and adipokines secreted by adipocytes at concentrations of 10 and 20 μM, which effectively reduced the adipogenic differentiation of hBM-MSCs and lipid accumulation in adipocytes. It also improved adipocyte function by lowering inflammatory cytokine secretion and increasing glucose uptake. For the first time, we show that G300 has the potential to be a novel therapeutic agent for the treatment of obesity and its related disorders.

New 1,2,3-Triazole-genipin Analogues and Their Anti-Alzheimer's Activity

A novel series of 1,2,3-triazole-genipin analogues were designed, synthesized, and evaluated for neuroprotective activity, acetylcholinesterase (AChE), and butyrylcholinesterase (BuChE) inhibitory activity. The genipin analogues bearing bromoethyl- and diphenylhydroxy-triazole showed in vitro neuroprotective properties against H₂O₂ toxicity along with potent inhibitory activity on BuChE with IC₅₀ values of 31.77 and 54.33 μM, respectively, compared with galantamine (IC₅₀ = 34.05 μM). The molecular docking studies of these genipin analogues showed good binding energy and interact well with the key amino acids of BuChE via hydrogen-bonding and hydrophobic interactions. Triazole genipins might be promising lead compounds as anti-Alzheimer's agents.

Click Chemistry in Natural Product Modification

Click chemistry is perhaps the most powerful synthetic toolbox that can efficiently access the molecular diversity and unique functions of complex natural products up to now. It enables the ready synthesis of diverse sets of natural product derivatives either for the optimization of their drawbacks or for the construction of natural product-like drug screening libraries. This paper showcases the state-of-the-art development of click chemistry in natural product modification and summarizes the pharmacological activities of the active derivatives as well as the mechanism of action. The aim of this paper is to gain a deep understanding of the fruitful achievements and to provide perspectives, trends, and directions regarding further research in natural product medicinal chemistry.

1,2,3-Triazole hybrids as anticancer agents: A review

Despite the advancements in the development of anticancer agents, more effective and safer anticancer drugs still need to be developed as the current agents cause unwanted side effects and many patients have become drug resistant. 1,2,3-Triazoles, due to their remarkable biological potential, have received considerable attention in drug discovery for the development of anticancer agents. The present review article presents an overview of the recent advances in 1,2,3-triazole hybrids with anticancer potential over the last 2 years, their chemical structures, structure-activity relationships, and mechanisms of action, as well as insights into the docking studies.

1,2,3-Triazole-Containing Compounds as Anti-Lung Cancer Agents: Current Developments, Mechanisms of Action, and Structure-Activity Relationship

Lung cancer is the most common malignancy and leads to around one-quarter of all cancer deaths. Great advances have been achieved in the treatment of lung cancer with novel anticancer agents and improved technology. However, morbidity and mortality rates remain extremely high, calling for an urgent need to develop novel anti-lung cancer agents. 1,2,3-Triazole could be readily interact with diverse enzymes and receptors in organisms through weak interaction. 1,2,3-Triazole can not only be acted as a linker to tether different pharmacophores but also serve as a pharmacophore. This review aims to summarize the recent advances in 1,2,3-triazole-containing compounds with anti-lung cancer potential, and their structure-activity relationship (SAR) together with mechanisms of action is also discussed to pave the way for the further rational development of novel anti-lung cancer candidates.
