Streptomyces Cytochrome P450 Enzymes and Their Roles in the Biosynthesis of Macrolide Therapeutic Agents
Review Biomol Ther 27(2), 127-133 (2019) Streptomyces Cytochrome P450 Enzymes and Their Roles in the Biosynthesis of Macrolide Therapeutic Agents Myung-A Cho, Songhee Han, Young-Ran Lim, Vitchan Kim, Harim Kim and Donghak Kim,* Department of Biological Sciences, Konkuk University, Seoul 05025, Republic of Korea Abstract The study of the genus Streptomyces is of particular interest because it produces a wide array of clinically important bioactive molecules. The genomic sequencing of many Streptomyces species has revealed unusually large numbers of cytochrome P450 genes, which are involved in the biosynthesis of secondary metabolites. Many macrolide biosynthetic pathways are catalyzed by a series of enzymes in gene clusters including polyketide and non-ribosomal peptide synthesis. In general, Streptomyces P450 enzymes accelerate the final, post-polyketide synthesis steps to enhance the structural architecture of macrolide chemistry. In this review, we discuss the major Streptomyces P450 enzymes research focused on the biosynthetic processing of macrolide therapeutic agents, with an emphasis on their biochemical mechanisms and structural insights.

Cytostatics As Hazardous Chemicals in Healthcare
REVIEW PAPER International Journal of Occupational Medicine and Environmental Health 2019;32(2):141 – 159 https://doi.org/10.13075/ijomeh.1896.01248 CYTOSTATICS AS HAZARDOUS CHEMICALS IN HEALTHCARE WORKERS’ ENVIRONMENT ANNA PAŁASZEWSKA-TKACZ, SŁAWOMIR CZERCZAK, KATARZYNA KONIECZKO, and MAŁGORZATA KUPCZEWSKA-DOBECKA Nofer Institute of Occupational Medicine, Łódź, Poland Department of Chemical Safety Abstract Cytostatics not only induce significant side-effects in patients treated oncologically but also pose a threat to the health of occupationally exposed healthcare workers: pharmacists, physicians, nurses and other personnel. Since the 1970s numerous reports from various countries have documented the contamination of working areas with cytostatics and the presence of drugs/metabolites in the urine or blood of healthcare employees, which di- rectly indicates the occurrence of occupational exposure to these drugs. In Poland the significant scale of occupational exposure to cytostatics is also confirmed by the data collected in the central register of occupational carcinogens/mutagens kept by the Nofer Institute of Occupational Medicine. The assessment of occupational exposure to cytostatics and health risks constitutes employers’ obligation. Unfortunately, the assessment of occu- pational risk resulting from exposure to cytostatics raises a number of concerns. Provisions governing the problem of workers’ health protection are not unequivocal because they derive from a variety of law areas, especially in a matter of hazard classification and safety data sheets for cytostatics. Moreover, no legally binding occupational exposure limits have been set for cytostatics or their active compounds, and analytical methods for these substances airborne and biological concentrations are lacking. Consequently, the correct assessment of occupational exposure to cytostatics, the eval- uation of health hazards and the development of the proper preventive strategy appear difficult. -

Resistance‐Guided Isolation and Characterization of Antibiotic‐Producing Bacteria from River Sediments Nowreen Arefa1, Ashish Kumar Sarker2 and Md
Arefa et al. BMC Microbiology (2021) 21:116 https://doi.org/10.1186/s12866-021-02175-5 RESEARCH ARTICLE Open Access Resistance‐guided isolation and characterization of antibiotic‐producing bacteria from river sediments Nowreen Arefa1, Ashish Kumar Sarker2 and Md. Ajijur Rahman1* Abstract Background: To tackle the problem of antibiotic resistance, an extensive search for novel antibiotics is one of the top research priorities. Around 60% of the antibiotics used today were obtained from the genus Streptomyces. The river sediments of Bangladesh are still an unexplored source for antibiotic-producing bacteria (APB). This study aimed to isolate novel APB from Padma and Kapotakkho river sediments having the potential to produce antibacterial compounds with known scaffolds by manipulating their self-protection mechanisms. Results: The antibiotic supplemented starch-casein-nitrate agar (SCNA) media were used to isolate antibiotic-resistant APB from the river sediments. The colonies having Streptomyces-like morphology were selectively purified and their antagonistic activity was screened against a range of test bacteria using the cross-streaking method. A notable decrease of the colony-forming units (CFUs) in the antibiotic supplemented SCNA plates compared to control plates (where added antibiotics were absent) was observed. A total of three azithromycin resistant (AZR) and nine meropenem resistant (MPR) isolates were purified and their antagonistic activity was investigated against a series of test bacteria including Shigella brodie, Escherichia coli, Pseudomonas sp., Proteus sp., Staphylococcus aureus,andBacillus cereus. All the AZR isolates and all but two MPR isolates exhibited moderate to high broad-spectrum activity. Among the isolates, 16S rDNA sequencing of NAr5 and NAr6 were performed to identify them up to species level. -

[E.Mail:[email protected] ] Received ; revised Antagonistic Streptomyces spp. were isolated from marine and mangrove sediment samples collected off Cochin, along the southwest coast of India. Sediment samples were pre-treated and following the soil dilution technique, samples were surface plated on starch casein agar and actinomycetes isolation agar. In the primary screening, 7.4% of presumptive actinomycetes (135 isolates) showed antibacterial activity against one or more bacterial fish pathogens and 3.7% of these cultures showed broad spectrum activity against the tested pathogens. Morphologically white powdery colonies with chalky white /grey appearance were selected as presumptive Streptomyces cultures. Isolates subjected to biochemical, physiological and 16S rDNA characters revealed the presence of three species of Streptomyces dominated by Streptomyces tanashiensis followed by S. viridobrunneus and S. bacillaris. Isolates characterized by 16S rDNA indicated the presence of 650 bp band in Streptomyces spp. Primary screening for activity against selected fish pathogens was done by a cross streak method using modified nutrient agar medium. Prominent isolates showing high zone of activity against the fish pathogens ranged 17-35 mm by the paper disc method. Enriched broth of selected isolates showing high antagonistic activity was screened for pharmacologically active agents revealed ethyl acetate fractions to be active against selected microbial pathogens. -
Persistent Gestational Trophoblastic Disease Is Potentially Fatal, but the Majority of Patients Are Cured with Chemotherapy
British Journal of Cancer (2000) 82(9), 1547–1552 © 2000 Cancer Research Campaign DOI: 10.1054/ bjoc.2000.1176, available online at http://www.idealibrary.com on Persistent gestational trophoblastic disease: results of MEA (methotrexate, etoposide and dactinomycin) as first-line chemotherapy in high risk disease and EA (etoposide and dactinomycin) as second-line therapy for low risk disease LS Dobson, PC Lorigan, RE Coleman and BW Hancock Gestational Trophoblastic Disease Centre, Weston Park Hospital, Sheffield, UK Summary Persistent gestational trophoblastic disease is potentially fatal, but the majority of patients are cured with chemotherapy. Any developments in treatment are therefore being directed towards maintaining efficacy and reducing toxicity. We evaluated efficacy and toxicity of methotrexate, etoposide and dactinomycin (MEA) as first-line therapy for high risk disease and etoposide and dactinomycin (EA) as second-line therapy for methotrexate-refractory low risk disease in a retrospective analysis of 73 patients (38 MEA, 35 EA) treated since 1986 at a supra-regional centre. The median follow-up period was 5.5 years and the median number of cycles received was 7. The overall complete response rate was 85% (97% for EA, 75% for MEA). Of eight patients who failed to respond, four have since died and four were cured with platinum-based chemotherapy. Alopecia was universal. Grade II or worse nausea, emesis, or stomatitis was observed in 29%, 30% and 37% respectively. Fifty-one per cent experienced grade II/III anaemia, 8% grade II or higher thrombocytopenia and 64% grade III or IV neutropenia; in six cases this was complicated by sepsis.
