Abstract
Oleanolic acid/rhodamine B hybrids exhibit different cytotoxicity depending on the way these two structural elements are linked. While a hybrid holding a piperazinyl spacer at C-28 proved to be cytotoxic in the nano-molar concentration range, hybrids with a direct linkage of the Rho B residue to C-3 of the triterpenoid skeleton are cytotoxic only in the low micro-molar concentration range without any selectivity. This once again underlines the importance of selecting the right spacer and the most appropriate position on the skeleton of the triterpene to achieve the most cytotoxic hybrids possible.

Abstract
Background:
Oleanolic Acid (OA) is a ubiquitous product of triterpenoid compounds.
Due to its inexpensive availability, unique bioactivities, pharmacological effects and non-toxic
properties, OA has attracted tremendous interest in the field of drug design and synthesis. Furthermore,
many OA derivatives have been developed for ameliorating the poor water solubility and bioavailability.
Objective:
Over the past few decades, various modifications of the OA framework structure have led
to the observation of enhancement in bioactivity. Herein, we focused on the synthesis and medicinal
performance of OA derivatives modified on A-ring. Moreover, we clarified the relationship between
structures and activities of OA derivatives with different functional groups in A-ring. The future application
of OA in the field of drug design and development also was discussed and inferred.
Conclusion:
This review concluded the novel achievements that could add paramount information
to the further study of OA-based drugs.

Abstract
The World Health Organization (WHO) has reported that cancer is one of the most prevalent diseases and a leading cause of death worldwide. Many anticancer drug development studies have been pursued over the last few decades and several viable drugs have been discovered, such as paclitaxel, topotecan and irinotecan. Previously, our research group uncovered the cytocidal and cytostatic effects of the plant Stephania delavayi Diels. In this study, we determined the active chemical to be 6,7-di-O-acetylsinococuline (FK-3000). The FK-3000 half maximal inhibitory concentration (IC50) in MDA-MB-231 breast carcinoma cells at 48 h was 0.52 µg/ml and it induced apoptosis in a dose- and time-dependent manner. FK-3000 suppressed NF-κB nuclear translocation, decreased NF-κB phosphorylation, and decreased COX-2 protein expression. MDA-MB-231 xenografted mice were treated with FK-3000, Taxol, or their combination for 21 days. The tumor size was smallest in the co-treatment group, indicating that FK-3000 may have a synergistic effect with Taxol. FK-3000 treatment showed no adverse effects on blood cell counts, serum protein levels, or pathology. These studies demonstrate that FK-3000, isolated from S. delavayi Diels., is a promising, pathway-specific anticancer agent that exhibits low toxicity.

Abstract
During the last few decades more and more attention has been paid to triterpenes-a group of compounds with five- or four-ring skeleton and carboxyl, hydroxyl or oxo groups. Triterpenes with unsubstituted C-3 hydroxyl group can be easily transformed into appropriate ketones and then into oximes. The carbonyl group can be created not only from the hydroxyl group at C-3 position, but also at C-2, C-12 or C-28 positions. Several methods of creation of two = NOH groups within one molecule of triterpene are known. There are also known triterpenes with two carbonyl groups, e.g. at C-3 and C-11 positions, which differ in reactivity: among them only C-3 group can be transformed into oxime. A reactive hydroxyimine group can undergo the action of acylating agents, such as carboxylic acids or their derivatives, also the ones with significant pharmacological activity. Acyl derivatives of triterpenic oximes exhibit important pharmacological activity. The biological tests performed with the use of cell cultures inoculated with viruses showed inhibitory activity of some triterpenic acyloximes against type 1 HSV (H7N1), ECHO-6 and HIV-1 viruses. Another acylated oximes derived from triterpenes shown cytotoxic or antiproliferative activity against many lines of cancer cells. In many cases the pharmacological effects of the tested acyloxyiminotriterpenes were comparable to those of appropriate standard drugs. One of the newest application of acyl derivatives of triterpenic oximes is their ability to form organogels.

Abstract
3alpha-methoxyserrat-14-en-21beta-ol (1) and 3beta-methoxyserrat-14-en-21beta-ol (2) and their conjugates with curcumin, kojic acid, quercetin, and baicalein (3-18), as well as new analogs (19-24) derived from 1 and 2, were tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). The inhibitory effects of 16 (IC50=330 mol ratio/32 pmol/TPA), 9 (IC50=335), 10 (IC50=338), and 15 (IC50=350) were stronger than those of the other compounds and the positive control, oleanolic acid (IC50=449). Compounds 15 and 16, which are conjugates of one molecule each of 1 or 2 and quercetin, inhibited mouse skin tumor promotion in an in vivo two-stage carcinogenesis model. The in vivo two-stage mouse skin carcinogenesis test employed 7,12-dimethylbenz[a]anthracene (DMBA) as an initiator and TPA as a promoter.

Abstract
In attempts to discover anti-HIV agents from natural sources, various traditional medicine extracts were tested for their inhibitory effects on HIV-1 proliferation and its protease. An extract of the seeds of Croton tiglium showed potent inhibitory effects on the proliferation of HIV-1. The active principle was determined to be phorbol esters. Several derivatives of phorbol ester were evaluated for inhibition of proliferation as well as activation of protein kinase C (PKC). Of these compounds, 12-O-acetylphorbol 13-decanoate (6) showed the most potent inhibition of proliferation without activating PKC. Some triterpenes from the stems of Cynomorium songaricum and the woody part of Xanthoceras sorbifolia showed inhibitory activity against HIV-1 protease. Various derivatives of oleanolic acid were synthesized and evaluated for their inhibitory activity against HIV-1 protease. Their inhibitory mechanism was also investigated.
