Background. The extract of Andrographis paniculata (Burm. F.) Wall. Ex. Nees. (sambiloto) (穿心蓮 chuān xīn lián) has been reported to have an antidiabetic effect on mice models and has been used traditionally in the community. The exact mechanism of sambiloto extract in decreasing plasma glucose is unclear, so we investigated the role of sambiloto extract in the incretin pathway in healthy and prediabetic subjects. Methods. This study was a randomized, placebo-controlled, crossover, double-blind trial. It included 38 people who were healthy and 35 people who had prediabetes. All subjects were randomly assigned to receive either the intervention sambiloto extract or a placebo. All subjects were randomly assigned to receive the first intervention for 14 days. There was a washout period between subsequent interventions. The primary outcome was glucagon-like peptide 1 (GLP-1) concentration, and secondary outcomes were fasting insulin, 2-hour postprandial insulin, homeostasis model assessment of insulin resistance (HOMA-IR), fasting blood glucose, 2-hour postprandial blood glucose, dipeptidyl peptidase-4 (DPP-4), and glycated albumin before and after the intervention. Result. After the intervention, GLP-1 concentration significantly increased in prediabetes by 19.6% compared to the placebo ( p = 0.043 ). There were no significant differences in the changes of fasting insulin, 2-hour postprandial insulin, HOMA-IR, fasting blood glucose, 2-hour postprandial blood glucose, DPP-4, and glycated albumin levels after the intervention. Sambiloto extract did not inhibit the DPP-4 enzyme in healthy and prediabetic subjects. Conclusion. Sambiloto extract increased GLP-1 concentration without inhibiting the DPP-4 enzyme in prediabetic subjects. This trial is registered with ClinicalTrials.gov (ID: NCT03455049), registered on 6 March 2018—retrospectively registered (https://clinicaltrials.gov/ct2/show/NCT03455049).

Background: Andrographis paniculata (AP) crude extract has been widely used in Thailand to treat mild COVID-19 infection since early 2020; however, supporting evidence was lacking. Purpose: To evaluate the efficacy of AP compared with standard treatment among hospitalised mild COVID-19 patients. Study design: Single-centre retrospective cohort study Methods: We collected data between March 2020 and August 2021 from COVID-19 patients admitted to one hospital in Thailand. Patients whose infection was confirmed by Real-Time Polymerase Chain Reaction (RT-PCR) and had normal chest radiography were included, whereas those receiving favipiravir or had unclear chest X-rays at admission were excluded. Participants were categorised as either AP or standard of care and followed for pneumonia confirmed by chest radiography. Multiple logistic regression was used to analyse the main results controlling for age, sex, history of having diabetes, hypertension, receiving statins, and antihypertensive drugs. Results: 605 out of 1,054 patients were included in the analysis. Of these, 59 patients (9.8%) developed pneumonia during the median follow-up of 7 days. The incidence rates of pneumonia were 13.93 (95%CI 10.09, 19.23) and 12.47 (95%CI 8.21, 18.94) per 1,000 person-days in AP and standard of care group, respectively. Compared to the standard of care group, the odds ratios of having pneumonia in the AP group were 1.24 (95%CI 0.71, 2.16; unadjusted model) and 1.42 (95%CI 0.79, 2.55; fully adjusted model). All sensitivity analyses produced consistent findings with the main results. Conclusion: We do not have sufficient evidence to show the efficacy of AP in mild COVID-19 infection. Interestingly, we observed the potentially harmful signal of using AP. While waiting for insights from ongoing trials, the use of AP in this condition should be done with caution.

Background: Andrographis paniculata is a herbaceous plant in the Acanthaceae family, that is widely used as a traditional medicine in Asian countries and known to exhibit a wide range of pharmacological effects. Recent studies have provided an overview of the great potential of A. paniculata as an analgesic. The ethanol extract and ethyl acetate (EA) fraction of A.paniculata were shown to contain diterpene lactone compounds, which may be useful as a potential active ingredient in analgesic drugs. The development of a herbal medicine based drug requires an effective and high quality active ingredient. Therefore, this research was aimed to compare the analgesic activity of ethanol extract and EA fraction based on their andrographolide content and further to determine the more viable active substance for analgesic herbal medicine based drug development. Method: The andrographolide content in the ethanol extract and EA fraction was determined by High Pressure Liquid Chromatography (HPLC). Measurement of analgesic activity was performed by writhing test. The experimental animals were randomly divided into eight groups consisting of 5 mice in each. Group 1 (negative control) received 1% Tween-80 in normal saline. Group 2 (positive control) received a standard analgesic drug (diclofenac sodium) at a dose of 40 mg/kg body weight. Group 3, 4, and 5 received ethanol extract while Group 6, 7, and 8 received EA fraction, each at a dose of 12.5, 25, and 50 mg andrographolide/kg body weight, respectively. Each mouse was injected intraperitoneally with 1% acetic acid at a dose of 10 ml/kg body weight 30 minutes after oral administration of the treatments. The number of writhes were counted 5 min after acetic acid injection over a period of 45 min. Results: Andrographolide content in ethanol extract and EA fraction was 15.66±0.28 and 21.25±1.08 % w/w, respectively. Ethanol extract and EA fraction displayed analgesic activity of 67.68% and 70.91% respectively, at a dose of 50 mg andrographolide/kg body weight. The positive control at a dose of 40 mg/kg body weight showed an analgesic activity of 74.33%. Statistical analysis showed no significant differences between EA fraction at a dose of 50 mg andrographolide/kg body weight and ethanol extract at the same dose as well as the positive control (P> 0.05). The effective dose 50% (ED50) of the ethanol extract and EA fraction was determined to be 29.49 and 25.55 mg/kg body weight, respectively. Conclusion: It was possible to use andrographolide content as an indicator for the analgesic activity of A.paniculata. Ethanol extract and EA fraction of A. paniculata at the same dose of andrographolide showed similar analgesic activity. The amount of ethanol extract which needed to reach similar analgesic activity was higher than EA fraction. Therefore, EA fraction likely has greater potential as an analgesic active substance due to its higher content of andrographolide; however further study is needed to develop it as a dosage form.

Background: Andrographolide (Andro) is a diterpenoid component of the plant Andrographis paniculata that is known for its anti-tumor activity against a variety of cancer cells.   Methods: We studied the effects of Andro on the viability of the human leukemia monocytic cell line THP-1 and the human multiple myeloma cell line H929. Andro was compared with cytosine arabinoside (Ara-C) and vincristine (VCR), which are well-established therapeutics against hematopoietic tumors. The importance of reactive oxygen species (ROS) production for the toxicity of each agent was investigated by using an inhibitor of ROS production, N-acetyl-L-cysteine (NAC).    Results:  Andro reduced the viability of THP-1 and H929 in a dose-dependent manner. H929 viability was highly susceptible to Andro, although only slightly susceptible to Ara-C. The agents Andro, Ara-C, and VCR each induced apoptosis, as shown by cellular shrinkage, DNA fragmentation, and increases in annexin V-binding, caspase-3/7 activity, ROS production, and mitochondrial membrane depolarization. Whereas Ara-C and VCR increased the percentages of cells in the G0/G1 and G2/M phases, respectively, Andro showed little or no detectable effect on cell cycle progression. The apoptotic activities of Andro were largely suppressed by NAC, an inhibitor of ROS production, whereas NAC hardly affected the apoptotic activities of Ara-C and VCR.  Conclusions: Andro induces ROS-dependent apoptosis in monocytic leukemia THP-1 and multiple myeloma H929 cells, underlining its potential as a therapeutic agent for treating hematopoietic tumors. The high toxicity for (thus forming: The high toxicity for H929 cells, by a mechanism that is different from that of Ara-C and VCR, is encouraging for further studies on the use of Andro against multiple myeloma.) H929 cells, by a mechanism that is different from that of Ara-C and VCR, is encouraging for further studies on the use of Andro against multiple myeloma.
