The effect might be positive and vice versa. Interaction might occur pharmacokinetics or pharmacodynamically. The study aimed to review potential interaction of metformin and some herbs with various pharmacological activities. Methods: This literature review was conducted by collecting articles with keywords Metformin, Herb-drug Interaction, drug interaction, pharmacokinetics, pharmacodynamics, and pharmacology from international databases such as Science Direct, PubMed, Springer Link, and Scopus up to 2021. Results: Metformin with its various uses such as antidiabetic agent, an agent for reducing weight for patients that sensitive or even resistant to insulin, patients with obesity, anti-tumor agent, anti-cancer potential agent, and also has anti-aging potential. Metformin could interacted with drugs, herbs, and also some bioactive isolate. The interaction might occurs pharmacokinetically or pharmacodynamically. Pharmacokinetics interactions occurred during distribution and also excretion via transporters that metformin transported with. This was shown as the elevated or lowered metformin levels in blood. Pharmacodynamic interactions can be seen as the lowering or elevated levels of glucose, HbA1c and even the lipid profile in blood or plasma. Conclusion: According to this literature review, Metformin have potential interaction with drugs, herbs, and also some bioactive isolate. The interactions occur pharmacokinetically or pharmacodynamically. This study can be used as a established familiarity with and understanding the potential HDIs from Metformin and herbal products.

Aerial Parts Authors: M. Abou Zeid, Ehsan Abstract: Introduction: Salvia hispanica L. is an annual herbaceous plant commonly known as "Chia", native of southern Mexico and northern Guatemala. The aim of this study is isolation, identification of secondary metabolites and evaluation of biological activities of ethyl acetate fraction of Salvia hispanica L. aerial parts. Methods: Air dried powdered of Salvia hispanica L. aerial parts was extracted by maceration and fractionated using light petroleum, dichloromethane and ethyl acetate solvents. Ethyl acetate fraction was subjected to column and thin layer chromatography for isolation of secondary metabolites that are characterized by UV-Vis, FT-IR, EI-MS, 1D and 2D NMR spectral analyses. UPLC-ESI-MS/MS technique was used on the same fraction. In-vitro biological evaluation of the fraction carried out for anti-oxidant activity using DPPH assay, anti-obesityactivity using pancreatic lipase inhibitory assay,anti-diabetic activity usingα -amylase inhibition assay andanti-cancer activities usingcell viability assay. Results: Six compounds were isolated including 1,2,4,5 tetrahydroxy benzene (1), leucantho flavone (2), rhamnetin (3), apigenin-7-O-β- D-glucoside(4), rosmarinic acid (5) and kaempferol-7-O-β-D-glucoside (6). The identification of thirty seven compounds byUPLC-ESI-MS/MS analysis. A strong DPPH scavenging activity with IC50 13.11compared to ascorbic acid, anti-obesity activity with IC50 59.3 compared to orlistate, anti-diabetic activity with IC50 95.2 compared to acarbose. High cytotoxic activity against lung carcinoma, colon carcinoma and moderately cytotoxic activity against prostate carcinoma cell lines. Conclusions: Salvia hispanica L. is a strong antioxidant and anti-carcinogenic against lung and colon cancer.

Hence, it remains a major challenge to decide what potential therapeutic regimens to treat COVID-19 patients. This study aims to investigate curcumin and virgin coconut oil (VCO) effects on cytokine levels (IL-1β, IL-2, IL-6, IL-18, TNF-α, and IFN-β) in COVID-19 patients. Methods: This study was a single-center, controlled trial with a parallel Arm or a Randomized Clinical trial design. A total of sixty COVID-19 patients admitted to the Universitas Sebelas Maret Hospital, Surakarta, Indonesia, were divided into two groups. The first group, consisting of 30 patients, was treated with Azithromycin 500 mg + Oseltamivir 2×75 mg + Hydroxychloroquine 400 mg/day for 5 days. The second group, comprising 30 patients, was treated with Azithromycin 500 mg + Oseltamivir 2×75 mg + Hydroxychloroquine 400 mg/day for 5 days, added with VCO 30 mL and curcumin 3×1 g/day for 21 days. The cytokine profiles of the serum samples were analyzed by the enzyme-linked immunosorbent assay (ELISA) on days 1, 14, and 21. Results: Our study showed that the second group had a significant reduction in IL-1β, IL-2, IL-6, TNF-α, and IFN-β levels after being treated with standard therapy added with curcumin and VCO on day 21 (p<0.05). Conclusion: These results suggested that curcumin and VCO might benefit the treatment of COVID-19 patients.

This study aims to investigate the effects of a combination of astaxanthin extracted from Hematococcus pluvialis microalga and palm tocotrienols rich-fraction (TRF) on inflammatory reaction in lipopolysaccharide (LPS)-stimulated mouse RAW 264.7 macrophages cells. MTT assay was used to test cell viability and nitrite oxide (NO) was determined using Griess assay. Isobologram confirmed that the combined treatment produced synergistic effect and measurement of inflammatory cytokines such as interleukin 6 (IL-6) and interleukin 12 (IL-12) through ELISA assay. Our results showed that the combination of astaxanthin and TRF exhibited inflammatory markers such as NO production. The concentration of astaxanthin ranging from 10 to 100 μg/mL and TRF at 4-25 μg/mL had no toxicity and achieved higher cell viability. The combination treatments led to more potent inhibition of NO production compared to single treatments. Combination Index (CI) was achieved from the combination treatments at IC80, resulting in synergism at a CI value of 0.81. Furthermore, ELISA showed that the combined treatment significantly further reduced the expression levels of pro-inflammatory cytokines IL-6 and IL-12. Our findings suggest that the combination of astaxanthin and TRF enhanced anti-inflammatory and antioxidant activities in stimulated macrophages and may act synergistically to produce health effects reducing inflammation.
