Abstract
Three new antiplasmodial compounds, named akedanones A (1), B (2), and C (3), were discovered from the cultured material of Streptomyces sp. K20-0187 isolated from a soil sample collected at Takeda, Kofu, Yamanashi prefecture in Japan. The structures of compounds 1-3 were elucidated as new 2,3-dihydronaphthoquinones having prenyl and reverse prenyl groups by mass spectrometry and nuclear magnetic resonance analyses. Compound 1 and the known furanonaphthoquinone I (4) showed potent in vitro antiplasmodial activity against chloroquine-sensitive and chloroquine-resistant Plasmodium falciparum strains, with half-maximal inhibitory concentration values ranging from 0.06 to 0.3 μM. Compounds 1 and 4 also displayed potent in vivo antiplasmodial activity against drug-sensitive rodent malaria Plasmodium berghei N strain, with inhibition rates of 47.6 and 43.1%, respectively, on intraperitoneal administration at a dose of 5 mg kg-1 day-1 for 4 days.

Their structures were elucidated based on spectroscopic data analysis, including IR, NMR, HRESIMS and ECD measurements. Additional known compounds, namely, hydroxysesamone (1), anthrasesamone A (2), 2,6-dimethoxy-1,4-benzoquinone (9), syringic acid (10), syringaresinol (11), 2,3-epoxysesamone 8-O-β-d-glucopyranoside (12), 2,3-diacetylmartinoside (13), 2,3-epoxy-4,5,8-trihydroxy-2-prenyl-1-tetralone (14), ursolic acid (15), chlorosesamone (16), 2,3-epoxysesamone (17), and 2-(4-methyl-3-pentenyl)anthraquinone (18) were isolated. The antiproliferative activity of the compounds was tested against the RPMI 8226 multiple myeloma cell line. When compounds presented an IC50 value <10 μM, they were tested against two other multiple myeloma cell lines, MM.1S and MM.1R. Compound 17 was found to be the most potent, with IC50 values of 0.6, 0.7, and 0.9 μM, respectively, for the three cell lines.

Abstract
The major issue of the current era is an unbalanced and poor diet like unhealthy fast foods, the main cause of various diseases. Most nutraceutical and pharma industries formulating the medicines from artificial sources are expensive and have several side effects. However, scientists are making efforts to find out the natural sources of medicines for the betterment of human health and treatment of diseases. Simultaneously, the worldwide preferences have shifted from artificial to natural resources and unconventional crops (i.e., oilseeds as protein source) and foods are becoming part of regular diet in most of the community, nutraceutical, and pharma industries. Sesame (SesamumindicumL.) is one of the unconventional crops providing multiple benefits due to its special bioactive components, such as sesamin, sesaminol, and gamma-tocopherol, and fatty acids composition like unsaturated fatty acids (i.e., oleic acid, linoleic acid, stearidonic acid, palmitoleic acid, and traces of linolenic acid). Sesame seed oil supplementation not only improves the quality of snack frying oils but also plays a key role in the formation of good quality healthy snack foods. Moreover, its seeds and oil play imperative role in the formulation of medicines utilized for different ailments. The current review highlights the importance and utilization of sesame seed and oil in pharmaceuticals, nutraceuticals, and food (especially snacks) industries.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sesamum indicum L. (Pedaliaceae) is an annual plant, which has been domesticated for well over 5000 years. It is widely cultivated for its seeds and is one of the oldest known oilseed crops. Traditionally, its seeds, seed oil, and different organs of the plant have been used to treat various diseases or conditions like ulcers, asthma, wound healing, amenorrhea, hemorrhoids, inflammations, etc. AIM OF THE REVIEW: The main aim of this review is to provide an outline and to assess the reported ethnopharmacological, phytochemical, pharmacological and toxicological studies of Sesamum indicum L. MATERIALS AND METHODS An extensive literature survey was done on various search engines like PubMed, Web of Science, Scopus, SciFinder, Google Scholar, Science direct, etc. Other literature sources like Wikipedia, Ethnobotanical books, Chapters were also studied to get maximum information possible on the Sesamum indicum L. RESULTS Over 160 different phytochemical compounds have been characterized and isolated from seeds, seed oil, and various plant organs, including lignans, polyphenols, phytosterols, phenols, anthraquinones, naphthoquinones, triterpenes, cerebroside, fatty acids, vitamins, proteins, essential amino acids, and sugars using suitable analytical techniques (e.g., LC-MS, GC-MS, HPTLC, HPLC). All the reported pharmacological activities like antioxidant, anticancer, antipyretic, antihypertensive, hepatoprotective, and anti-inflammatory are due to the virtue of these phytochemical compounds. CONCLUSION This review mainly highlights the botanical aspect of Sesamum indicum and its phytochemical constituents, ethnomedicinal uses, different pharmacological activities followed by ongoing clinical trials and future prospects. Sesamum indicum has great importance in traditional Indian medicine, which is further supported by modern pharmacological studies, especially in hepatoprotection, inflammation, and cancer. Several researchers have suggested that Sesamum indicum extracts and isolated compounds could have a wide therapeutic potency range. More research is needed to uncover key features of Sesamum indicum in medical practice, such as structure-activity relationships, toxicity, and therapeutic potential. In order to fully explore the plant's potential, safety assessments and implementation of an integrated cultivation method are also areas that need to investigate.

Abstract
An organocatalytic enantioselective epoxidation of 2,3-disubstituted naphthoquinones with tert-butyl hydroperoxide as an oxidant was developed using a guanidine-urea bifunctional catalyst lacking C2 symmetry, which was designed based upon the insights obtained from the DFT calculation model for our previous C2 symmetric catalyst. The present organocatalytic reaction provides access to a variety of optically active naphthoquinone epoxides bearing aryl and methyl substituents at C2 and C3 in high yields with high enantioselectivities (up to 97:3 er).

Abstract
An enantioselective nucleophilic epoxidation of 2-substituted 1,4-naphthoquinones in the presence of a newly developed guanidine-bisurea bifunctional organocatalyst with tert-butyl hydroperoxide (TBHP) as an oxidant is presented. 1,4-Naphthoquinones bearing substituents at C6, C7, and C2 were available for the reaction, and the corresponding epoxides were obtained with 88:12-95:5 er in 71-98% yields. DFT calculations indicated that substituents at C2 and C6 in the terminal Ar group of the catalyst 9k play a key role in controlling the stereochemical outcome.

Abstract
Sudanese folk medicine represents a unique blend of indigenous cultures with Islamic, Arabic and African traditions. In addition, Sudan encompasses different terrains and climatic zones, ranging from desert and semi-desert in the north to equatorial with a short rainy season (semi-aridand semi-humid) in the centre to equatorial with a long rainy season (arid-humid and equatorialhumid) in the south. This variation contributes to the immense diversity of vegetation in the region. The flora of Sudan consists of 3137 species of flowering plants belonging to 170 families and 1280 genera. It is estimated that 15% of these plants are endemic to Sudan. The intersection of diverse cultures and the unique geography holds great potential for Sudanese herbal medicine. Medicinal and aromatic plants and their derivatives represent an integral part of life in Sudan. Indigenous remedies are the only form of therapy available to the majority of poor people. It has been estimated that only 11% of the population has access to formal health care. Therefore, research on the desired pharmacological effects and possible unwanted side effects or toxicity is required to improve efficacy and safety of Sudanese herbal medicine. In the future, it would be preferable to promote the use of traditional herbal remedies by conversion of raw plant material into more sophisticated products instead of completely replacing the traditional remedies with synthetic products from industrialized countries. The present review gives an overview of traditional Sudanese medicinal and aromatic herbs and their habitats, traditional uses, and phytochemical constituents.

Abstract
Three anthraquinones, named anthrasesamones A, B and C, were isolated from the roots of Sesamum indicum, and their respective structures were determined to be 1-hydroxy-2-(4-methylpent-3-enyl)anthraquinone, 1,4-dihydroxy-2-(4-methylpent-3-enyl)anthraquinone and 2-chloro-1,4-dihydroxy-3-(4-methylpent-3-enyl)anthraquinone on the basis of spectroscopic evidence. Two known anthraquinones were also isolated for the first time from S. indicum roots and characterized as 2-(4-methylpent-3-enyl)anthraquinone and (E)-2-(4-methylpenta-1,3-dienyl)anthraquinone. Anthrasesamone C is a rare chlorinated anthraquinone in higher plants.
