Abstract
Four new polyketide derivatives, pestalotiopols A–D (1–4), together with seven known compounds (5–11), were isolated from a chemical-epigenetic culture of Pestalotiopsis sp. The structures and absolute configurations of the new compounds (1–4) were determined by spectroscopic analyses, Mo2-induced CD, and electronic circular dichroism (ECD) calculations. All the isolated compounds (1–11) were tested for their cytotoxic activities. Among these compounds, compounds 1, 2, 6 and 7 exhibited cytotoxicity against four human cancer cell lines with IC50 values of 16.5–56.5 μM. The structure–activity relationships of compounds (1–11) were examined. The results indicated that both the diol system of the side chain and the aldehyde group might contribute to the cytotoxic activity. The possible biosynthetic pathways for compounds (1–4) were also postulated. Four new polyketide derivatives, pestalotiopols A–D (1–4), together with seven known compounds (5–11), were isolated from a chemical-epigenetic culture of Pestalotiopsis sp.![]()

Streptomyces thermoviolaceus SRC3 strain as a novel source of the antibiotic adjuvant streptazolin: A statistical approach toward the optimized production. J Microbiol Methods 2018; 148:161-168. [PMID: 29665368 DOI: 10.1016/j.mimet.2018.04.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2018] [Revised: 04/05/2018] [Accepted: 04/12/2018] [Indexed: 10/17/2022]
Abstract
Streptomyces thermoviolaceus SRC3, a newly isolated actinobacterial strain from Algerian river sediments, exhibited a broad activity against various bacterial and yeast human pathogens (Salmonella Typhi ATCC 14028, Vibrio cholerae ATCC 14035, MRSA ATCC 43300 and Candida albicans ATCC 10231). The strain SRC3 was selected from thirty nine actinobacterial isolates and identified as S. thermoviolaceus based on morphology, cultural properties, physiological analyses and 16S rRNA gene sequencing. Culture parameters for the antibiotic production were optimized by sequential statistical strategy including Plackett-Burman design (PBD) and Response Surface Methodology (RSM). In PBD experiments, KCl, K2HPO4, MgSO4·7H2O, pH value and incubation time emerged as the most significant in affecting the output of antimicrobial activities. These factors were further optimized using Central Composite Design (CCD). The best achieved conditions were: KCl (0.01%), K2HPO4 (0.1%), MgSO4·7H2O (0.02%) and 9 days incubation for anti-S. Typhi compounds, KCl (0.051%), MgSO4·7H2O (0.05%) and 5 days incubation for C. albicans inhibitors. The metabolite responsible for the bioactivities was purified, structurally characterized (by NMR, MS, UV and IR analyses) and identified as streptazolin, recently reported as a promising antibiotic adjuvant.

Abstract
Twelve previously undescribed polyketide derivatives, heterocornols A-L, and seven known analogues were isolated from a culture of the fungus Pestalotiopsis heterocornis associated with sponge. Their structures were elucidated by a comprehensive spectroscopic data analysis and CD Cotton effects. These compounds were evaluated for cytotoxic and antibacterial activities in vitro. Among them, heterocornols A-C, F-H, methyl-(2-formyl-3-hydroxyphenyl)propanoate, agropyrenol, and vaccinol G exhibited cytotoxicities against four human cancer cell lines with IC50 values 15-100 μM, and they also showed antibacterial activities against Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis with MIC values ranging from 25 to 100 μg/mL. Moreover, compounds heterocornol C, heterocornol G, agropyrenol, and vaccinol G showed weak antifungal activities against Candida parapsilosis and Cryptococcus neoformans with MIC values 100 μg/mL.
