10-Hydroxyoleoside dimethyl ester

Virtual screening of active compounds from jasminum lanceolarium and potential targets against primary dysmenorrhea based on network pharmacology.[Pubmed:32693616]

Nat Prod Res. 2020 Jul 22:1-4.

In present study, multi-target and multi-pathway mechanisms of Jasminum lanceolarium Roxb (JL) on primary dysmenorrhea (PDM) treatment were predicted by the approach of network pharmacology and molecular docking, leading to the obtaining of 22 predicted targets for 69 compounds in JL. The Compound-Target analysis displayed intimate association among targets and compounds. Meanwhile, the Compound-Target-Target revealed PTGS2, OPRD1 and NOS3 were the key targets with intensive interaction. The Compound-Target-Pathway network indicated these pathways were closely related to hormone regulation, central analgesia, spasmolysis and inflammation. The anti-inflammation pathways might be the key mechanism of JL for the treatment of PDM based on KEGG pathway enrichment analysis and pharmacological experiment, and 10-Hydroxyoleoside dimethyl ester might be a promising leading compound due to its good molecular docking scores and previous experimental evaluation.

Multifloroside Suppressing Proliferation and Colony Formation, Inducing S Cell Cycle Arrest, ROS Production, and Increasing MMP in Human Epidermoid Carcinoma Cell Lines A431.[Pubmed:31861384]

Molecules. 2019 Dec 18;25(1). pii: molecules25010007.

Multifloroside (4), together with 10-hydroxyoleoside 11-methyl ester (1), 10-Hydroxyoleoside dimethyl ester (2), and 10-hydroxyligustroside (3), are all secoiridoids, which are naturally occurring compounds that possess a wide range of biological and pharmacological activities. However, the anti-cancer activity of 1-4 has not been evaluated yet. The objective of this work was to study the anti-cancer activities of 1-4 in the human epidermoid carcinoma cell lines A431 and the human non-small cell lung cancer (NSCLC) cell lines A549. The results indicate that 1-4 differ in potency in their ability to inhibit the proliferation of human A431 and A549 cells, and multifloroside (4) display the highest inhibitory activity against A431 cells. The structure-activity relationships suggest that the o-hydroxy-p-hydroxy-phenylethyl group may contribute to the anti-cancer activity against A431 cells. Multifloroside treatment can also inhibit cell colony formation, arrest the cell cycle in the S-phase, increase the levels of reactive-oxygen-species (ROS), and mitochondrial membrane potential (MMP), but it did not significantly induce cell apoptosis at low concentrations. The findings indicated that multifloroside (4) has the tendency to show selective anti-cancer effects in A431 cells, along with suppressing the colony formation, inducing S cell cycle arrest, ROS production, and increasing MMP.

Regioselective enzymatic acylation and deacetylation of secoiridoid glucosides.[Pubmed:19652419]

Chem Pharm Bull (Tokyo). 2009 Aug;57(8):882-4.

Candida antarctica lipase (CAL) catalyses the regioselective cinnamoylation and benzoylation of the aglycone moiety of 10-Hydroxyoleoside dimethyl ester a secoiridoid glucoside. This enzyme catalyses as well regioselective deacetylation of the aglycone moiety of 10,2',3',4',6'-pentaacetoxyoleoside dimethyl ester. Further action of the enzyme results in deacetylation at C-6' and C-4' of the glucoside moiety.

Regioselective enzymatic acetylation of the aglycone moiety of a secoiridoid glucoside. Two new secoiridoid glucoside acetates.[Pubmed:15340202]

Chem Pharm Bull (Tokyo). 2004 Sep;52(9):1123-4.

Candida antarctica lipase (CAL) catalyses the regioselective acetylation of the 10-hydroxyl group of 10-Hydroxyoleoside dimethyl ester, a secoiridoid glucoside, using THF as a solvent and ethyl acetate or vinyl acetate as acetyl group suppliers. Two acetyl derivatives at 3'- and 6'-sites of the glucosidic ring of 10-acetoxyoleoside dimethylester, not previously described, were obtained by acetylation in the same conditions.

Phytochemistry and the systematics and ecology of Loasaceae and Gronoviaceae (Loasales).[Pubmed:10948006]

Am J Bot. 2000 Aug;87(8):1202-10.

A screening for iridoid compounds of 78 of 315 species from all major groups in Gronoviaceae and Loasaceae has been carried out. The results were compared to the systematic concepts in the family and distribution and ecology of the taxa. Iridoids are present in at least some species of all genera screened. Some simple, monomeric compounds (e.g., loganin, sweroside) are found in all major groups of the two families and represent the basic iridoid inventory. Other compounds are restricted to certain taxonomic groups: nine-carbon iridoids (e.g., deutzioside) are restricted to Mentzelia (Loasaceae subfam. Mentzelioideae), hetero-oligomeric iridoids (e.g., tricoloroside methyl ester, acerifolioside) are restricted to two small groups in Loasa (Loasa ser. Macrospermae and ser. Floribundae, Loasaceae subfam. Loasoideae), and oleosides (e.g., 10-Hydroxyoleoside dimethyl ester) are restricted to the large genus Caiophora sensu Weigend). The distribution of certain iridoid compounds thus confirms some of the generic limits. Iridoid phytochemistry does not correlate with systematic entities above the generic level nor does it in any way correlate with the morphological evolution of taxa. Conversely, the amount and complexity of iridoid compounds present in taxa correlate positively with the aridity of their habitat and the extent of mammalian herbivore pressure.

New secoiridoid glucosides from Jasminum lanceolarium.[Pubmed:17252492]

Planta Med. 1996 Dec;62(6):515-8.

Two new secoiridoid glucosides, the trans-P-coumaroyl and trans-feruloyl esters of 10-hydroxyoleoside, jaslanceosides A (2) and B (3), were isolated from the leaves and stems of Jasminum lanceolarium (Oleaceae) in addition to jasminoside (1) and 10-Hydroxyoleoside dimethyl ester (8). The structures of these compounds have been elucidated on the basis of spectral and chemical methods.
