Introduction: Breast cancer is one of the major universal health problems affecting more than two million cases per year. Estrogen receptor alpha (ERα) and P53 are common targets for the treatment of breast cancer and are primarily involved in cell proliferation. The function of p53 protein is regulated by direct binding to MDM2 protein. Therefore, inhibition of p53-MDM2 interaction leads to reactivating p53 activity. Alkaloid compounds generally have potential anticancer effect. Alkaloid compound from Mitragyna speciosa have the potential for anticancer. Methods: The method used is molecular docking with AutoDockTools 1.5.6 program. Predict the properties of physicochemical, pharmacokinetic, and toxicity prediction tests (ADMET) using pkCSM. Results: The results showed that speciophylline, corynoxine A, and corynoxine B have the best values in free binding energy (ΔG) for estrogen receptor (ERα) alpha receptor. Meanwhile, mitraphylline, mitrafoline, and corynoxine B have the best values for protein P53. Predict ADMET using the pkCSM, the alkaloid compound has strong lipophilicity and good permeability so it predicts the ability to penetrate intestinal cell membranes and the skin membrane. Spesiofilin, mitraphylline, and mitrafolin are not expected hepatotoxic. Conclusion: Speciophylline and mitraphylline have potential as anticancer drugs through the inhibitory of estrogen receptor alpha and MDM2 reseptor.

Migraine is a sterile neurogenic inflammation of the trigeminal nerve which releases vasoactive neuropeptides and activates platelets to release vasoactive substances such as serotonin (5-HT). Platelet hyperaggregation occurs in the pathogenesis of migraine caused by one of the stimulatory factors 5-HT. Platelet aggregation is increased and 5-HT levels are elevated in the blood and brain in the early stages of migraine. Alkaloid β-carbolin alkaloids can increase monoamines in brain regions through inhibition of monoamine oxidase (MAO) and inhibition of 5-HT reuptake. Alkaloids in the ethanolic extract of SCE function as analgesics and anti-inflammatory which can reduce pain and improve blood circulation. Sargassum cristaefolium extract (SCE) was measured for its bioactive substance content. The extract was administered to an animal model of intraperitoneal nitroglycerin-induced migraine and examined for platelet levels, platelet aggregation and 5-HT. The results of statistical tests showed an increase in platelets (p\<0.05), an increase in platelet aggregation (p\<0.05) and a decrease in 5-HT (p\<0.05). The relationship between alkaloids and platelets; platelets and platelet aggregation; platelet aggregation and 5-HT and 5-HT levels and migraine incidence (p\<0.05). The alkaloids found in SCE can lower platelet count, decrease platelet aggregation and increase 5-HT levels in migraines.

Background: The focus on herbal plants as medicine is increasing rapidly because of their efficacy and less side effects. The medicinal plants are great alternative as they are renewable and non exhaustive resources. In India these medicinal plants have been part of the people{\textquoteright}s life dating back from centuries. Objectives: The present study is aimed to evaluate anatomical characterization of stem and root of Indigofera tirunelvelica Sanjappa for the first time which can be used in the identification and standardisation of Indigofera tirunelvelica Sanjappa. Results: The stem and root of the plant were evaluated for their microscopic features. In that histochemical localisation of secondary metabolites and transverse section of stem and root were studied. The histochemical localisation result reveals the presence of terpenoids, alkaloids, flavonoids and lignin were found in epidermal, cortical and xylem regions of the stem. Alkaloids, Terpenoids, phenols and lignin were found in the different areas of root. Conclusion: The present study thus emphasis the potentiality of the plant as a drug.

Introduction: Genus Phoebe have been reported to produce isoquinoline alkaloids as aporphines, noraporphines, and benzylisoquinolines. Many of these isolates exhibit diversified biological activities, including cytotoxic activity. Objective: The objective of this study is to determine cytotoxic activity of compound isolated from Phoebe declinata againts MCF-7 (breast cancer cell line). Methods: Extraction was done by reflux using n-hexane, antioxidant activity measured by DPPH method and reducing power method, cytotoxic activity measured by MTT assay using MCF-7 cell line, struture eucidation was confirmed by NMR. Results: The antioxidant activity measured using DPPH method for 1 and 2 showed IC50 value of 6.42 and 11.80 \μg/mL respectively and using reducing power method for 1 and 2 showed IC50 value of 7.02 and 13.74 \μg/mL respectively. Compound (1) and (2) exhibited cytotoxic activity against MCF-7 cells with an IC50 value of 82.978 and 93.179 \μg/mL. Conclusion: Compound (1) and (2) exhibited antioxidant activity and cytotoxic activity against MCF-7.

The susceptibility of five human pathogenic bacterial species to an alkaloids isolated from the leaves of this plant was screened using the agar well diffusion and broth micro-dilution assay. The purity of isolated alkaloids was checked by TLC and qualitative phytochemical analysis and total alkaloids were quantified. In the present study, the inhibitory action of the alkaloid was found to increase with an increase in concentration against all bacterial strains. The maximum zone of inhibition was observed at the concentration of 500 \μg/ml against all the bacteria. In this study, the S. aureus and E. coli are the more susceptible than the other selected human pathogenic bacteria. Based on the observations, E. alba appears to be a valuable source for antimicrobial properties and helps to produce antimicrobial agents to treat human pathogenic infections. Context: Different parts of Eclipta alba crude extracts are used traditionally for the treatment of several diseases of liver, skin and stomach.
