Abstract
Oleanolic acid (OA), a ubiquitous pentacyclic oleanane-type triterpene isolated from edible and medicinal plants, exhibits a wide spectrum of pharmacological activities and tremendous therapeutic potential. However, the undesirable pharmacokinetic properties limit its application and development. Numerous researches on structural modifications of OA have been carried out to overcome this limitation and improve its pharmacokinetic and therapeutic properties. This review aims to compile and summarize the recent progresses in the medicinal chemistry of OA derivatives, especially on structure-activity relationship in the last few years (2010-2021). It gives insights into the rational design of bioactive derivatives from OA scaffold as promising therapeutic agents.

Abstract
Saponins are a large family of amphiphilic glycosides of steroids and triterpenes found in plants and some marine organisms. By expressing a large diversity of structures on both sugar chains and aglycones, saponins exhibit a wide range of biological and pharmacological properties and serve as major active principles in folk medicines, especially in traditional Chinese medicines. Isolation of saponins from natural sources is usually a formidable task due to the microheterogeneity of saponins in Nature. Chemical synthesis can provide access to large amounts of natural saponins as well as congeners for understanding their structure-activity relationships and mechanisms of action. This article presents a comprehensive account on chemical synthesis of saponins. First highlighted are general considerations on saponin synthesis, including preparation of aglycones and carbohydrate building blocks, assembly strategies, and protecting-group strategies. Next described is the state of the art in the synthesis of each type of saponins, with an emphasis on those representative saponins having sophisticated structures and potent biological activities.

Abstract
Ulvan is a sulfated polysaccharide from green algae with potent antitumor, antiviral, and immunomodulatory activities. However, no chemical synthesis of ulvan saccharides has been reported to date. In this paper, we performed the first efficient synthesis of the unique sulfated tetrasaccharide motif of type B ulvanobiuronic acid 3-sulfate. Based on the gold(i)-catalyzed glycosylation with glycosyl ynenoates as donors, efficient construction of the challenging α-(1 → 4)-glycosidic bonds between iduronic acid and rhamnose building blocks was achieved to afford the tetrasaccharide skeleton in a stereospecific manner. The synthetic sulfated tetrasaccharide was found to significantly improve the phagocytic activity of macrophage RAW264.7 cells.

Abstract
An array of oleanolic acid-type saponins based on β-hederin has been synthesized in a linear or one-pot manner. The cell viability assays indicate that synthetic saponins show antiproliferation activities in three cancer cell lines with IC50 values of 2.4-15.1 μM and hederacolchiside A1 being the most potent. The results demonstrate that the type of terminal monosaccharides and linkage position have apparent effects on cytotoxicities and selectivities of these saponins against cancer cell lines tested. This study is helpful for future development of more potent anticancer leads.

Abstract
Pulsatillae radix is a conventional traditional Chinese medicine (TCM) with common name Baitouweng, and has notable effects on inflammation and dysentery. Pulsatilla chinensis (Bge.) Regel is the only source plant of Baitouweng recorded in Chinese Pharmacopoeia, but its adulteration often occurs in the market that possibly affects medicinal efficacy and safety. We have established an internal transcribed spacer 2 (ITS2) barcode library based on 105 plant samples from 12 Pulsatilla species and 10 common adulterants. Results indicate that ITS2 barcoding can accurately distinguish Pulsatilla species from their adulterants. Pulsatilla chinensis can be discriminated from 11 congeneric species by two stable single nucleotide polymorphisms (SNPs) in the ITS2 region. Additionally, a quick specific PCR-RFLP identification assay based on the ITS2 barcode was developed. Using specific primers ITS2/PR1 combined with restriction enzyme Bgl I, Pu. chinensis can rapidly be differentiated from other species via simple and low-cost test procedures. Furthermore, 30 commercial Baitouweng products were tested and only two products were derived from authentic Pu. chinensis. Thus, these two molecular approaches provide practical tools for quick identification of commercial Baitouweng products and can help ensure the safe use of this TCM product.

Abstract
A series of lupane-type saponins bearing OSW-1 disaccharide unit as well as its regio- and stereoisomers were prepared and used for the structure-activity relationships (SAR) study. Unexpected preference for 1→4-linked regioisomers and an unusual inversion of the conformation of the sugar rings were noted. Cytotoxic activity of new lupane compounds was evaluated in vitro and revealed that some saponins exhibited an interesting bioactivity profile against human cancer cell lines. Influence of the protecting groups on the cytotoxicity was investigated. These results open the way to the synthesis of various lupane-type triterpene and saponin derivatives as potential anticancer compounds.

Abstract
To test the effect of adding different monosaccharide groups to a non-phloem-mobile insecticide on the phloem mobility of the insecticide, a series of conjugates of different monosaccharides and fipronil were synthesized using the trichloroacetimidate method. Phloem mobility tests in castor bean ( Ricinus communis L.) seedlings indicated that the phloem mobility of these conjugates varied markedly. L-Rhamnose-fipronil and D-fucose-fipronil displayed the highest phloem mobility among all of the tested conjugates. Conjugating hexose, pentose, or deoxysugar to fipronil through an O-glycosidic linkage can confer phloem mobility to fipronil in R. communis L. effectively, while the -OH orientation of the monosaccharide substantially affected the phloem mobility of the conjugates.

Abstract
Three new triterpenoid saponins, polygonoides C (1), D (2), and E (3), were obtained from the ethanolic extract of the rhizome of Polygonatum sibiricum Redoute. On the basis of NMR and ESI-MS spectra, and chemical evidence, the structures of the three new compounds were elucidated as 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-3β,7β,22β-trihydroxy-oleanolic acid (1), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-3β,7β,22β-trihydroxy-oleanolic acid methyl ester (2), and 3-O-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→4)-[α-L-rhamno-pyranosyl-(1→2)]-β-D-glucopyranosyl-3β,21β-dihydroxy-oleanolic acid 28-O-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→3)-β-D-glucopyranoside (3).
