The present study evaluated a range of biological activities of selected millet types and sorghum varieties in Sri Lanka in relation to diabetes and its complications management. Five millet types, namely, proso millet, white finger millet, kodo millet, foxtail millet, and finger millet (Oshadha and Rawana), and two sorghum varieties, namely, sweet sorghum and sorghum ICSV 112, were used in this study. Methanolic extracts of whole grains were studied for antiamylase, antiglucosidase, and early- and middle-stage antiglycation and glycation reversing activities in vitro. Tested millets and sorghum showed significant ( p  < 0.05) and dose-dependent antiamylase (IC50: 33.34 ± 1.11–1446.70 ± 54.10 μg/ml), early-stage antiglycation (IC50: 15.42 ± 0.50–270.03 ± 16.29 μg/ml), middle-stage antiglycation (135.08 ± 12.95–614.54 ± 6.99 μg/ml), early-stage glycation reversing (EC50: 91.82 ± 6.56–783.20 ± 61.70 μg/ml), and middle-stage glycation reversing (393.24 ± 8.68–1374.60 ± 129.30 μg/ml) activities. However, none of the studied millet and sorghum showed antiglucosidase activity. Out of the samples studied, pigmented samples, namely, sweet sorghum, Oshadha, and Rawana, exhibited significantly high ( p  < 0.05) antiamylase and early- and middle-stage antiglycation and glycation reversing activities compared to other millet and sorghum samples. Interestingly, sweet sorghum exhibited nearly four times potent antiamylase activity compared to the standard drug acarbose (IC50 111.98 ± 2.68 μg/ml) and sweet sorghum, kodo millet, Oshadha, and Rawana showed comparable early-stage antiglycation activities in comparison to the reference standard Rutin (IC50 21.88 ± 0.16 μg/ml). Therefore, consumption of whole grains of pigmented millet and sorghum in Sri Lanka may play an important role in the prevention and management of diabetes and its complications. Interestingly, this is the 1st study to report all the tested biological activities for millet and sorghum in Sri Lanka and the 1st study to report both early- and middle-stage glycation reversing activities of millet and sorghum worldwide.

Nutraceutical Properties

Small millets are a group of six crops comprising of finger millet, kodo millet, little millet, foxtail millet, barnyard millet and proso millet. They are considered as nutri- cereals and are source of food, feed and fodder. The crops are grown in a variety of agro-ecological situations including plains, coast and hills as well as in diverse soils and varying rainfall. They are known for resilience and drought enduring capacity and are relatively less prone to major pests and diseases. The richness in calcium, dietary fiber, polyphenol and protein contents in millets make them unique among the cereals. Generally, millets show significant amounts of amino acids like methionine and cystine and also have high fat content than rice and maize. Millets have nutraceutical properties in the form of antioxidants which prevent deterioration of human health such as lowering blood pressure, risk of heart disease, prevention of cancer and cardiovascular diseases, diabetes, decreasing tumor cases etc. The contribution of millets to national food security and their potential health benefits, millet grain is now receiving increasing interest from food scientists, technologists and nutritionists.

Commonly consumed millet types viz., Little millet, foxtail millet, pearl millet, finger millet, and Kodo millet were tested under two processing methods of soaking and germination at a different time point. Most popular processing practices adopted by Indian households were studied for their influence on the biochemical properties, antioxidant profile, and anti-nutritive factors. The results showed that the sprouting process showed a maximum influence on the antioxidant and anti-nutritive factors. The comparative analysis of the five millets suggested 24h soaking and 24h germination was found to be best for producing nutritionally enriched millet products. Tannin content decreases with an increase in germination. The reduction in tannin was about 50% in little millet (0.347 mg/g) and the highest was recorded in finger millet (2.07 mg/g). The highest amount of saponin content was found in pearl millet( 39.53 mg/g) followed by finger millet ( 34.86 mg/g) with 24 hr soaking and  24 hr germination. The phytase activity was found to be higher in little millet (61.520 u/kg) when prolonged soaking and germination. The DPPH assay showed sprouted foxtail millet grains contain more antioxidant activity (81.13%) when extent the period of soaking and germination.

Tetrazole Derivatives

The creation of novel drugs containing a tetrazole ring as a structural fragment has contributed considerably to the outstanding achievements of the pharmaceutical chemistry in the last decade. Tetrazoles are the heterocyclic compounds having diverse biological activities such as analgesic, antiinflammation, antimicrobial, anticancer, antidiabetic, etc., and an impending source in biosciences. In this paper, the authors describe the synthesis of novel tetrazoles from N, N-( 6-Phenyl-1,3,5-triazine-2,4-diyl) dibenzamide (PTDDB) and 2-phenyl-4, 6-di(2H-tetrazole-2-yl)-1,3,5-triazine(5a-i) were prepared per the proposed scheme. A new class of tetrazole heterocycles were synthesised and characterised. I n vivo analysis was carried out on the analgesic property of synthesised tetrazole derivatives (5a, 5b, 5c). Characterisation studies such as IR, 1H NMR, 13C NMR, Mass and elemental analysis were performed for the synthesised tetrazole derivatives. Some of the tetrazole derivatives 5a, 5b, and 5c were tested for anodyne activity using morphine as the standard drug. The data reveals that all the three compounds 5a, 5b and 5c taken for the study show analgesic activity by hot plate method and tail flick methods. Among tested compounds, compound 5c is found to have potent analgesic (anodyne) activity. The results of the study indicate that the sample taken for the study show fairly good business using morphine as the standard drug.

Background: Novel coronavirus pneumonia (NCP), or coronavirus disease 2019 (COVID-19), is a worldwide health threat that has affected millions of people globally. Traditional Chinese medicine (TCM) has been introduced for the treatment of COVID-19. However, efficacy differs among herbal medicines, and the ideal prescription pattern for TCM herbal formulae for COVID-19 treatment needs to be explored. Therefore, the data mining method has been used in this study to analyze the TCM prescription pattern for COVID-19. Objective: The aim of this study was to analyze the TCM prescription pattern in Regional Schemes in China for COVID-19 in order to provide a new reference for the use of TCM in COVID-19 treatment. Method: By searching the TCM treatment protocols of COVID-19 in 23 Regional Schemes, TCM syndromes and herbal medicines were analyzed by data mining. The Ancient and Modern Medical Case Cloud Platform (V2.1 personal Edition) was used to perform frequency statistics, correlation analysis, and cluster analysis. A total of 82 TCM syndromes and 171 Chinese herbal medicines were found. The course of the disease can be divided into the early stage, middle stage, severe stage, and recovery stage. Results: In the early stage, the focus is primarily on resolving dampness, dispelling cold, and diffusing the lungs. In the middle stage, the treatment priority is clearing heat and resolving toxins, promoting lung function, and relieving asthma. In the severe stage, the focus is on tonifying Qi, restoring Yang, and relieving depletion of Yin and Yang. In the recovery stage, the main treatment is to invigorate the spleen and regulate Qi, tonify Qi, nourish Yin, and clear residual disease evil. There are certain differences between the Regional Schemes and the Nation Schemes, but the core prescription pattern of the former is consistent with the latter. The effectiveness of these 171 Chinese herbs include but are not limited to inhibiting COVID-19, strengthening immune system function, preventing heart failure, acting as antioxidants, oxidative stress inhibitory effects, maintaining organ function, and improving leukocyte survival. Conclusion: This study may help to improve understanding of TCM herbal prescription pattern, practices, reveal the efficacy of combinations of Chinese herbs, and provide new ideas for TCM treatment for COVID-19.

Introduction: Mycobacterium tuberculosis has instigated a serious challenge toward the effective treatment of tuberculosis. The reoccurrence of the resistant strains of the disease to accessible drugs/medications has mandate for the development of more effective anti-tubercular agents with efficient activities. Time expended and costs in discovering and synthesizing new hypothetical drugs with improved biological activity have been a major challenge toward the treatment of multi-drug resistance strain M. tuberculosis (TB). Meanwhile, to solve the problem stated, a new approach i.e. QSAR which establish connection between novel drugs with a better biological against M. tuberculosis is adopted. Methods: The anti-tubercular model established in this study to forecast the biological activities of some anti-tubercular compounds selected and to design new hypothetical drugs is subjective to the molecular descriptors; MATS7s, SM1_DzZ, SpMin4_Bhv, TDB3v and RDF70v. Ligand-receptor interactions between quinoline derivatives and the receptor (DNA gyrase) was carried out using molecular docking technique by employing the PyRx virtual screening software and discovery studio visualizer software. Furthermore, docking study indicates that compounds 20 of the derivatives with promising biological activity have the utmost binding energy of -17.79 kcal/mol. Results: Meanwhile, the interaction of the standard drug; isoniazid with the target enzyme was observed with the binding energy -14.6 kcal/mol which was significantly lesser than the binding energy of the ligand (compound 20).Therefore, compound 20 served as a template structure to designed compounds with more efficient activities. Among the compounds designed; compounds 20p was observed with better anti-tubercular activities with more prominent binding affinities of -24.3kcal/mol. Conclusion: The presumption of this research aid the medicinal chemists and pharmacist to design and synthesis a novel drug candidate against the tuberculosis. Moreover, in-vitro and in-vivo test could be carried out to validate the computational results.
