Usage

Description

Gracillin is a steroidal saponin derived from the rhizomes of the Dioscoreaceae family, specifically found in C. speciosus. It exhibits a range of biological activities, including anti-proliferative effects on various types of cancer cells and potential applications in other areas.

Uses

Used in Pharmaceutical Applications:
Gracillin is used as an anti-proliferative agent for its ability to reduce cell growth in a wide range of cancer cell lines, including leukemia, non-small cell lung, colon, CNS, prostate, melanoma, ovarian, renal, and breast cancers. Its effectiveness is demonstrated by its GI50s values ranging from 0.58-2.44 μM.
Used in Veterinary Medicine:
In the veterinary industry, gracillin is used as a treatment for the growth reduction of fish Ich parasite (I. multifiliis) theronts, with an EC50 value of 0.53 mg/L. It also induces significant mortality in I. multifiliis protomonts and encysted tomonts when used at a concentration of 0.8 mg/L. Additionally, gracillin can decrease the number of I. multifiliis-infected goldfish by approximately 75% when applied at a concentration of 1 mg/L in tank water.
Used in Anti-inflammatory Applications:
Gracillin is utilized as an anti-inflammatory agent, as demonstrated by its ability to reduce ear edema induced by arachidonic acid in mice when administered at a dosage of 100 mg/kg.

The substrate specificity of a glucoamylase with steroidal saponin-rhamnosidase activity from Curvularia lunata

In previous work, we studied and reported that an enzyme from Curvularia lunata 3.4381 had the novel specificity to hydrolyze the terminal rhamnosyl at C-3 position of steroidal saponin and obtained four transformed products; the enzyme was purified and ascertained as glucoamylase (EC 3.2.1.3 GA). In this work, the enzyme exhibiting steroidal saponin-rhamnosidase activity was systematically studied on 21?steroidal saponins and 6 ginsenosides. The results showed that the α-1,2-linked end-rhamnosyl residues at C-3 position of steroidal saponins could be hydrolyzed to corresponding secondary steroidal saponins, among which 18 compounds were isolated and identified, including 3 new secondary compounds. For the furostanosides having glucosyl residues at the C-26 position, hydrolysis occurred first at end-rhamnosyl at C-3 position to produce secondary furostanosides. The reaction of hydrolyzing glucosyl at C-26 position depended considerably on longer reaction times yielding the corresponding secondary spirostanosides (without rhamnosyl and glucosyl residues). The enzyme had the strict specificity for the terminal α-1,2-linked rhamnosyl residues of linear chain, or the terminal α-1,2-linked rhamnosyl residues with branched chain of 1,4-linked glycosyl residues of sugar chain at C-3 position of steroidal saponins, it was not specific for different aglycones, different glycons, and the number of glycon of sugar chain of steroidal saponin. The end-rhamnosyl of ginsenosides and p-nitrophenyl-α-l-rhamnopyranoside (pNPR) could not be hydrolyzed by the enzyme from C. lunata.
