Murraya paniculata [L.] Jack. (Kemuning) is a plant that grows widely in some areas of Indonesia. Studies related to this plant have been widely explored especially isolation of its active compounds. The plant contents several active compounds such as flanovoids. In the study, three flavonoid isolated from M. paniculata were evaluated for their effect on histamine release from mast cells (RBL-2H3 cells). These compounds were 3,3’,4’,5,5’,6,7,8-octamethoxyflavone; 3,3’,4’,5,5’,6,7-heptamethoxyflavone and 3, 3’, 4’, 5, 5’, 7–hexamethoxyflavone. The histamine inducers used in the study were DNP24-BSA dan thapsigargin, inducing the histamine release immunologically and non-immunologically, respectively. In the study, heptamethoxyflavone and hexamethoxyflavone did not influence the histamine release from mast cells significantly. However, octamethoxyflavone could increase the histamine release from RBL-2H3 cells in absence and presence the histamine inducers. The flavanoid could increase the release of histamine up to 50 %. Based on the results, polymethoxy moieties at the structure of flavonoid have a significant role to emerge the histamine-release stimulating effect from mast cells.

Disorders of carbohydrate metabolism can lead to diabetes mellitus. Carbohydrates are metabolized in the gastrointestinal tract into simple glucose and absorbed into the bloodstream and affected blood glucose levels. The absorption process is catalyzed by α- 1 ,4 - glycoside breaking bond enzyme , namely α - amylase and α -1 ,6 - glycoside breaking bond enzyme, namely α – glucosidase. They are found in the intestinal cells. Research had been conducted in an effort to develop an alternative treatment of diabetes mellitus by testing the ability of isolates of andrographolide in inhibiting α-amylase activity and α-glucosidase in vitro. Andrographolide isolates showed fairly good activity in inhibiting α-amylase ( IC50 = 1,.49 mg/mL) and weak in inhibiting α-glucosidase (IC50 = 38,86 mg/mL). Inhibition of α-amylase activity is evidence of one mechanism of andrographolide in reducing carbohydrate metabolism that can affect blood glucose levels and indicates that andrographolide is a potential alternative medicine in addressing diabetes mellitus .

Marmin is a coumarin derivative compounds isolated from the bark and roots of Aegle Marmelos Correa. Previously, ethanolic extract of leaves of Aegle Marmelos Correa on isolated ileum showed antagonism effect on the contraction induced by histamine. Besides H1 receptor, there is also muscarinic acetylcholine (AChM)receptors involved in the mechanism of ileum contraction. Marmin is predicted to antagonize on AChM3 receptors.This study aimed to determine the effect of marmin on smooth muscle contraction of isolated guinea pig ileum induced by metacholine, an agonist of AChM3 receptor. The method in the study were in vitro (isolated organ) and in silico (docking PLANTS). In the in vitro study, marmin exhibited a competitive antagonists effect at the concentration of 100 Î¼M (pA2 value of 1,728) on the AChM3 receptors. Reversibility assay on AChM3 receptors showed that by washing the ileum with Tyrode buffer every 6 minutes for 30 minutes, the bond of marmin to the receptor was still not completely detached. In the in silico study, marmin was observed to be bound to AchM3 receptors (docking score: -102.086). Marmin bond was weaker than that of native ligand of AChM3 receptor (tiotropium, docking score: -115.107), however, stronger than that of AChM3 receptor agonist and antagonist. Based on the results, we conclude that marmin have a competitive antagonist activity on AChM3 receptor.

Ginger had been reported to ameliorate painful diabetic neuropathy (PDN) in an animal model. Gingerol and shogaol were active compounds of ginger that potentially act on transient receptor potential cation channel subfamily V member 1 (TRPV1), a key receptor in PDN. This study aims to predict the binding of gingerol and shogaol to TRPV1 using an in silico model. The ligands of the docking study were 3 chemical compounds of each gingerol and shogaol, i.e. 6-shogaol, 8-shogaol, 10-shogaol, 6-gingerol, 8 gingerol and 10-gingerol. Capsaicin, a TRPV1 agonist, was used as a native ligand. The TRPV1 structure was taken from Protein Data Bank (ID 3J9J). The docking analysis was performed using Autodock Vina. The result showed that among the ginger active compounds, 6-shogaol had the strongest binding energy (-7.10 kcal/mol) to TRPV1. The 6-shogaol lacked the potential hydrogen bond to Ile265 of TRPV1 protein, which capsacin had. However, it's binding energy towards TRPV1 was not significantly different compared to capsaicin. Therefore, 6-shogaol had potential to be developed as a treatment for PDN.
