triterpenoid/dental caries

In this work, we reported a biocompatible nature product-based soft material which could convert heavy metals to nanoparticles (NPs) in situ spontaneously in a simple step. We have designed and synthesized a natural triterpenoid-tailored phosphate (methyl glycyrrhetate phosphate (MGP)), and this

Many of oleanolic and ursolic pentacyclic triterpenoid isomers generally coexist. There is a small difference in their structures. Based on coordination chromatography theory, a reversed-phase high-performance thin-layer chromatography (HPLC) method has been investigated for improving the isomers'

Ilexgenin A (IA) is a novel pentacyclic triterpenoid, which extracted from leaves of Ilex hainanensis Merr. In the present study, we aim to explore anti-inflammatory activity of IA on LPS-induced peritonitis and its underlying molecular mechanism. The results determined that IA was capable of

This paper focuses on the study of the separation mechanism of oleanane and ursane pentacyclic triterpenoid isomers by a coordination chromatographic method. Based on the calculation analysis, beta-cyclodextrin (beta-CD) and its derivatives were selected as the suitable agents. The experimental

In a previous work, we reported the regulatory role of the triterpenoids on 5-hydroxytryptamine (5-HT)3A receptors activity in Xenopus laevis oocytes (Eur. J. Pharmacol., 615, 2009, Lee et al.). In the present report, we studied the modulation of triterpenoids on the activity of the human nicotinic

Wilbrandia ebracteata (WE), a Brazilian medicinal plant used in folk medicine for the treatment of rheumatic diseases, displays anti-inflammatory properties and constitutes a rich source of cucurbitacins and cucurbitacin-related compounds. The current study investigated the potential

OBJECTIVE The aim of this study was to examine the effect of ursolic acid (UA) and oleanolic acid (OA), triterpenoid compounds that are isolated from many edible and medicinal plants, on cariogenic microorganisms and biofilms. METHODS A microtitre plate dilution assay was used to determine the

OBJECTIVE To examine if steroid-like compounds found in many Chinese medicinal products conventionally used for the promotion of blood circulation may act as active components via the same molecular mechanism triggered by cardiac glycosides, such as ouabain. METHODS The inhibitory potency of ouabain

There is a definite relationship between the dietary consumption of sucrose and the incidence of dental caries. Noncaloric sucrose substitutes for use in the sweetening of foods, beverages, and medicines may be either synthetic compounds or natural products. In the United States, four potently sweet

Betulinic acid (BA), a pentacyclic triterpenoid, is a very promising therapeutic drug with varied medicinal properties but it has low water solubility and consequentially low bioavailability. Cyclic β-(1→3),(1→6)-glucans (CBG), microbial cyclooligosaccharides produced by Bradyrhizobium japonicum

BACKGROUND Two regions of squalene-hopene cyclase (SHC) were examined to define roles for motifs posited to be responsible for initiation and termination of the enzyme-catalyzed polyolefinic cyclizations. Specifically, we first examined the triple mutant of the DDTAVV motif, a region deeply buried

BACKGROUND The squalene:hopene cyclases (SHCs) are bacterial enzymes that convert squalene into hopanoids, a function analogous to the action of oxidosqualene cyclases (OSCs) in eukaryotic steroid and triterpenoid biosynthesis. We have identified the binding site for a selective, potent,

Dental caries is considered a multi-factorial, infectious, chronic, localized, post-eruptive, transmissible disease that leads to the destruction of dental hard tissue. The recognition of Streptococcus mutans as the major bacterial species involved in dental caries has led to the implementation of

OBJECTIVE Dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. This study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such

Ziziphus jujuba Mill., jujube, leaf infusions are popular bedtime beverages as they improve sleep by soothing the nerves. With the aim of providing further insights into the polyphenol content of jujube leaf infusion and their antioxidant activities, a 2,2-diphenyl-1-picrylhydrazyl (DPPH)-guided
