Abstract
In this work, a total of 19 novel naphthalene hybrids with chimonanthine scaffolds were efficiently synthesised from indole-3-acetonitrile in good yields. The prepared compounds were evaluated for biological activity against Cryptococcus neoformans, Escherichia coli, Shigella spp, Candida albicans, Salmonella spp, and Staphylococcus aureus. The preliminary bioassays showed that most of the synthesised compounds exhibited significant antibacterial or antifungal activity. Notably, compound 8 showed potent activity against Cryptococcus neofonmans, Escherichia coli, Shigella spp, and Candida albicans than the positive control, all with the same MIC value of 3.53 µM. Compound 8 had a broad spectrum of antibacterial or antifungal activity, and will be studied further.

Abstract
To search for efficient agricultural antifungal lead compounds, 39 Chimonanthus praecox derivatives were designed, synthesized, and evaluated for their antifungal activities. The structures of target compounds were fully characterized by 1H NMR, 13C NMR, and MS spectra. The preliminary bioassays revealed that some compounds exhibited excellent antifungal activities in vitro. For example, the minimum inhibitory concentration (MIC) of compound b15 against Phytophthora infestans was 1.95 µg mL−1, and the minimum inhibitory concentration (MIC) of compound b17 against Sclerotinia sclerotiorum was 1.95 µg mL−1. Therefore, compounds b15 and b17 were identified as the most promising candidates for further study.

Abstract
Starting from L-tryptophan, 19 new N-substituted chiral indole analogs were synthesized. The prepared compounds were evaluated for biological activity against Sclerotinia sclerotiorum, Alternaria solani, Verticillium dahliae, Colletotrichum orbiculare, Cytospora juglandis and Curvularia lunata. The preliminary bioassays showed that most of the synthesized compounds exhibited fungicidal activity. Compound b13 in particular exhibited significant antifungal activity against Verticillium dahliae and Sclerotinia sclerotiorum, with the MIC value of 1.95 µg mL-1. Compound b13 also showed excellent activity against six plant pathogen fungi, and was identified as the most active on the biological assays, and will be studied further.

Abstract
A series of calycanthaceous alkaloid analogs have been synthesized in excellent yields. All the target compounds were evaluated in vitro for biological activity against a broad range of plant pathogen fungi, bacteria and human pathogenic fungi, and some of the designed compounds exhibited potential activity in the primary assays. Notably, Compound b7 illustrated higher degrees of activity against Aspergillu sflavu than amphotericin B, with a minimal inhibitory concentration value of 15.63 µg·mL−1. Compound b7 displayed the most effective activity among the tested calycanthaceous analogs and might be a novel potential leading compound for further development of antifungal agent.

Abstract
Heterocyclic compounds play a significant role in various biological processes of the human
body and many of them are in clinical use due to their diverse, chemical and biological properties.
Among these, indole is one of the most promising pharmacologically active molecules. Due to its
chemical reactivity, indole has been willingly modified to obtain a variety of new lead molecules,
which has been successfully utilized to obtained novel drug candidates for the treatment of different
pharmacological diseases. Indole-based compounds such as vincristine (anticancer), reserpine (antihypertensive),
amedalin (antidepressant) and many more describe the medicinal and pharmacological
importance of the indole in uplifting human life. In this review, we compiled various reports on indole
derivatives and their biological significance, including antifungal, antiprotozoal, antiplatelet, anti-
Alzheimer’s, anti-Parkinson’s, antioxidant and anticancer potential from 2015 onwards. In addition,
structure-activity relationship studies of the different derivatives have been included. We have also
discussed novel synthetic strategies developed during this period for the synthesis of different indole
derivatives. We believe that this review article will provide comprehensive knowledge about the medicinal
importance of indoles and will help in the design and synthesis of novel indole-based molecules
with high potency and efficacy.

NEAU-HV9: Isolation, Identification, and Potential as a Biocontrol Agent against Ralstonia Solanacearum of Tomato Plants. Microorganisms 2020; 8:microorganisms8030351. [PMID: 32121616 PMCID: PMC7142955 DOI: 10.3390/microorganisms8030351] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Revised: 02/04/2020] [Accepted: 02/12/2020] [Indexed: 11/24/2022] Open
Abstract
Ralstonia solanacearum is an important soil-borne bacterial plant pathogen. In this study, an actinomycete strain named NEAU-HV9 that showed strong antibacterial activity against Ralstonia solanacearum was isolated from soil using an in vitro screening technique. Based on physiological and morphological characteristics and 98.90% of 16S rRNA gene sequence similarity with Streptomyces panaciradicis 1MR-8T, the strain was identified as a member of the genus Streptomyces. Tomato seedling and pot culture experiments showed that after pre-inoculation with the strain NEAU-HV9, the disease occurrence of tomato seedlings was effectively prevented for R.solanacearum. Then, a bioactivity-guided approach was employed to isolate and determine the chemical identity of bioactive constituents with antibacterial activity from strain NEAU-HV9. The structure of the antibacterial metabolite was determined as actinomycin D on the basis of extensive spectroscopic analysis. To our knowledge, this is the first report that actinomycin D has strong antibacterial activity against R. solanacearum with a MIC (minimum inhibitory concentration) of 0.6 mg L−1 (0.48 μmol L−1). The in vivo antibacterial activity experiment showed that actinomycin D possessed significant preventive efficacy against R. solanacearum in tomato seedlings. Thus, strain NEAU-HV9 could be used as BCA (biological control agent) against R. solanacearum, and actinomycin D might be a promising candidate for a new antibacterial agent against R. solanacearum.
