Actinobacteria are one of the best natural libraries for discovering drugs. Various commercial drugs have been developed against infectious and metabolic disorders from actinobacteria; however, there is no report on their simultaneous inhibitory effect against diabetes, a life-threatening disease, and its related pathological processes, like inflammation and vascular calcification (VC). In this research, after several screening, Nocardia sp. UTMC 751 was introduced as the first microbial source exhibiting a simultaneous inhibitory activity on the targets, including hyperglycaemia and protein glycation, and other involved pathological processes like inflammation and VC.

Background: Apiaceae fruits as common spices used for prevention of many chronic diseases including cancer. Objective: The present study compared the biological effects of different fruits from various Apiaceae tribes to compare and find the fraction source(s) with potential characteristics for further investigation including cancer prevention. Methods: Fruits of Apium graveolens L. (celery), Bunium persicum (Boiss.) B.Fedtsch. (black cumin), Petroselinum crispum (Mill.) Fuss (parsley), Pimpinella anisum L. (anise), Trachyspermum ammi (L.) Sprague (ajwain), Coriandrum sativum L. (coriander), Foeniculum vulgare Mill. (fennel), Anethum graveolens L. (dill), Heracleum persicum Desf. ex Fisch., C.A.Mey. & Avé-Lall. (Persian hogweed), Ferula assa-foetida L. (asafoetida), Cuminum cyminum L. (cumin)and Daucus carota L. (carrot) were extracted with 80 % methanol and fractionated by petroleum ether, chloroform, ethyl acetate and methanol, respectively. For different fractions and total extract of all 12 samples, cytotoxicity by brine shrimp test (BST) and MTT assay against cancer and normal cell (foreskin fibroblast cells), antioxidant effects by FRAP, and total phenols by Folin-Ciocalteu method were measured. Results: The general toxicity of ethyl acetate fractions (mean of data) was higher than others in the brine shrimp test (P < 0.05). The most cytotoxic fractions against colon carcinoma (HT-29), breast adenocarcinoma (MDA-MB-231) and alveolar basal epithelial adenocarcinoma (A549) cell lines were from Ammineae and Peucedaneae tribes while fruits fractions with high phenol contents and antioxidant powers were from Ammineae tribe. Conclusion: The Apiaceae fruits have significant biological effects, therefore the isolation of phytochemical compounds from active fractions with cytotoxicity is suggested in future studies.
