Cytotoxic constituents from Helicteres hirsuta collected in Vietnam.[Pubmed:30445838]
Nat Prod Res. 2018 Nov 16:1-5.
Phytochemical study on the extract of Vietnamese medicinal plant Helicteres hirsuta Lour. has led to the isolation and structural elucidation of twelve secondary metabolites, 3-O-trans-caffeoylbetulinic acid (1), 3beta-benzoylbetulinic acid (2), Betulinic acid methyl ester (3), betulinic acid (4), lupeol (5), 4-hydroxybenzoic acid (6), 3,4-dihydroxybenzoic acid methyl ester (7), 4-hydroxy-3,5-dimethoxybenzoic acid (8), 5,8-dihydroxy-7,4'-dimethoxyflavone (9), isoscutellarein 4'-methyl ether 8-O-beta-D-glucopyranoside (10), methyl caffeate (11) and stigmasterol (12). Especially, compound 2 was reported as a new natural product. Their structures were elucidated by a combination of 2D NMR and ESI-FT-ICR-MS spectroscopies. Furthermore, eight compounds were tested for their cytotoxicity against five cancer cell lines (Hela, HepG2, SK-LU-1, AGS and SK-MEL-2). The results showed that compounds (1, 3-5, 9) have moderate activities. This is the first study on the chemical constituents and their cytotoxicity of the Vietnamese Helicteres hirsuta L.
Synthesis of cytotoxically active derivatives based on alkylated 2,3-seco-triterpenoids.[Pubmed:28923388]
Eur J Med Chem. 2017 Nov 10;140:74-83.
Extremely low content of biologically active triterpenoids with the fragmented or contracted ring A extractable from plants is the main disadvantage of their use in drug discovery and practical pharmacology. Development of new methods for synthesis of these compounds and their structural analogs from bioavailable triterpene precursors gives an opportunity to obtain promising agents for pharmacology with excellent yields. A new approach to synthesis of alkylated A-seco-triterpenoids, including the Beckmann fragmentation of 3-methyl-substituted allobetulin or Betulinic acid methyl ester with 2-hydroxyimino group in the ring A was proposed. These compounds were used to prepare a series of 2,3-seco- and five-membered ring A lupane and oleanane derivatives, cytotoxicity of which was screened in vitro against the cancer (HEp-2, HCT 116, A549, RD TE32, MS) and non-cancerous (HEK 293) cell lines. Methyl 3-bromomethyl-1-cyano-3-oxo-2,3-seco-2-norlup-20(29)-en-30-al-28-oate was selected as the most active compound (IC50 3.4-10.4 muM for HEp-2, HCT 116, RD TE32, MS cells) capable of triggering caspase-8-mediated apoptosis in HCT 116 cells accompanied by typical apoptotic chromatin condensation, without any loss of mitochondrial membrane permeability.
Antiprotozoal activity of betulinic acid derivatives.[Pubmed:19748254]
Phytomedicine. 2010 Apr;17(5):379-82.
Betulinic acid (1), isolated from the crude extract of the leaves of Pentalinon andrieuxii (Apocynaceae), together with betulinic acid acetate (2), betulonic acid (3), Betulinic acid methyl ester (4), and betulin (5) were evaluated for their antiprotozoal activity. The results showed that modifying the C-3 position increases leishmanicidal activity while modification of the C-3 and C-28 positions decreases trypanocidal activity.
A new dihydrodibenzodioxinone from Hypericum x 'Hidcote'.[Pubmed:19535015]
Fitoterapia. 2009 Jun;80(4):226-9.
One new compound, 4-hydroxy-4a,7-dimethoxy-4,4a-dihydrodibenzo-p-dioxin-2(3H)-one (1), was isolated from the aerial parts of the hybrid Hypericum x 'Hidcote', together with 8 known compounds: caryophyllene-4,5-epoxide, quercetin, quercitrin, quercetin-3-O-beta-D-galactopyranoside, epicatechin, Betulinic acid methyl ester, beta-sitosterol and beta-sitosterol glucoside. The structure of the new compound, as well as its absolute configuration, was established by means of spectroscopic data analyses, including 2D NMR spectroscopy and X-ray structural analysis.
Antimalarial activity of betulinic acid and derivatives in vitro against Plasmodium falciparum and in vivo in P. berghei-infected mice.[Pubmed:19367418]
Parasitol Res. 2009 Jul;105(1):275-9.
Malaria is one of the most important tropical diseases and mainly affects populations living in developing countries. Reduced sensitivity of Plasmodium sp. to formerly recommended antimalarial drugs places an increasing burden on malaria control programs as well as on national health systems in endemic countries. The present study aims to evaluate the antimalarial activity of betulinic acid and its derivative compounds, betulonic acid, betulinic acid acetate, Betulinic acid methyl ester, and Betulinic acid methyl ester acetate. These substances showed antiplasmodial activity against chloroquine-resistant Plasmodium falciparum parasites in vitro, with IC(50) values of 9.89, 10.01, 5.99, 51.58, and 45.79 microM, respectively. Mice infected with Plasmodium berghei and treated with betulinic acid acetate had a dose-dependent reduction of parasitemia. Our results indicate that betulinic acid and its derivative compounds are candidates for the development of new antimalarial drugs.
Isolation of betulinic acid, its methyl ester and guaiane sesquiterpenoids with protein tyrosine phosphatase 1B inhibitory activity from the roots of Saussurea lappa C.B.Clarke.[Pubmed:19136914]
Molecules. 2009 Jan 8;14(1):266-72.
Activity-guided fractionation of a MeOH extract of the roots of Saussurea lappa C.B.Clarke (Compositae), using an in vitro protein tyrosine phosphatase 1B (PTP1B) inhibition assay, led to the isolation of four active constituents: betulinic acid (1), Betulinic acid methyl ester (2), mokko lactone (3) and dehydrocostuslactone (4), along with nine inactive compounds. Our findings indicate that betulinic acid (1) and its methyl ester 2, as well as the two guaiane sesquiterpenoids 3 and 4 are potential lead moieties for the development of new PTP1B inhibitors.
Melanogenesis inhibitory compounds from Saussureae Radix.[Pubmed:18409040]
Arch Pharm Res. 2008 Mar;31(3):294-9.
Ten compounds were isolated from the EtOAc soluble part of the MeOH extract of Saussureae Radix, with their effects on melanin production also evaluated in B-16 mouse melanoma cell lines stimulated with 3-isobutyl-1-methylxanthine (IBMX), an elevator of cellular cAMP. The compounds were identified as aplotaxene (1), 1 beta-hydroxy arbusculin A (2), costunolide (3), dehydrocostuslactone (4), 11 beta,13-dihydrocostunolide (5), reynosin (6), heptadec-(9Z)-enoic acid (7), beta-sitosterol (8), linoleic acid methyl ester (9) and Betulinic acid methyl ester (10). Compounds 2, 9 and 10 were identified from Saussureae Radix for the first time. Furthermore, compounds 2, 3 and 6 showed potent inhibitory effects on the IBMX-induced melanogenesis, in dose-dependent manners, with IC50 values of 11, 3 and 2.5 microg/mL, respectively. As a positive control, arbutin exhibited an IC50 value of 29 microg/mL.
Lanostane-type triterpenoids from Diospyros discolor.[Pubmed:17541192]
Chem Pharm Bull (Tokyo). 2007 Jun;55(6):908-11.
Four new lanostane-type triterpenes, 24-ethyl-3beta-methoxylanost-9(11)-en-25-ol (1), 3beta-methoxy-24-methylenelanost-9(11)-en-25-ol (2), 3beta-methoxy-25-methyl-24-methylenelanost-9(11)-en-21-ol (3) and 3beta-methoxy-24-methyllanosta-9(11),25-dien-24-ol (4) together with three known triterpenes, betulinaldehyde, Betulinic acid methyl ester, and ursaldehyde have been isolated from the methanol extract of the twigs of Diospyros discolor. The structures of those new compounds were elucidated by spectroscopic methods.
