“…In 2009, iso-α-cyclopiazonic acid (213), along with its isomer 210, was structurally characterized in the marine algae-derived A. flavus C-F-3 [169], the marine prawn-derived A. flavus OUCMDZ-2205 [170], and marine-derived P. camemberti [171]. Two new CPA derivatives, amycocyclopiazonic acid (214) and amycolactam (215), were isolated from a sponge-associated rare actinomycete Amycolatopsis sp.…”

Tetramic acid (pyrrolidine-2,4-dione) compounds, isolated from a variety of marine and terrestrial organisms, have attracted considerable attention for their diverse, challenging structural complexity and promising bioactivities. In the past decade, marine-derived microorganisms have become great repositories of novel tetramic acids. Here, we discuss the biological activities of 277 tetramic acids of eight classifications (simple 3-acyl tetramic acids, 3-oligoenoyltetramic acids, 3-decalinoyltetramic acid, 3-spirotetramic acids, macrocyclic tetramic acids, N-acylated tetramic acids, α-cyclopiazonic acid-type tetramic acids, and other tetramic acids) from marine-derived microbes, including fungi, actinobacteria, bacteria, and cyanobacteria, as reported in 195 research studies up to 2019.

“…Each gliding bacterial isolate was cultivated in a 250 ml Erlenmeyer flask containing 100 ml of SAP2 broth medium and 2 g of amberlite XAD-16 resins (Sangnoi et al 2008, 2009, 2014; Spyere et al 2003). The cultivation flasks were incubated and shaken at 200 rpm for 7 days at 25 °C.…”

“…The resins were collected using a nylon mesh and rinsed with deionized water to remove unwanted cells and other contaminants. Resins were left to dry at room temperature for 15 min and also soaked in 100 ml methanol for 1 h. Methanolic phases were separated from the resins, and methanolic crude extracts were obtained after evaporating a methanol solvent (Sangnoi et al 2008, 2009, 2014). Crude extracts were prepared to a final concentration of 25 mg/ml in DMSO.…”

The study aimed to screen and isolate strains of freshwater aquatic gliding bacteria, and to investigate their antibacterial activity against seven common pathogenic bacteria. Submerged specimens were collected and isolated for aquatic gliding bacteria using four different isolation media (DW, MA, SAP2, and Vy/2). Gliding bacteria identification was performed by 16S rRNA gene sequencing and phylogenetic analysis. Crude extracts were obtained by methanol extraction. Antibacterial activity against seven pathogenic bacteria was examined by agar-well diffusion assay. Five strains of aquatic gliding bacteria including RPD001, RPD008, RPD018, RPD027 and RPD049 were isolated. Each submerged biofilm and plastic specimen provided two isolates of gliding bacteria, whereas plant debris gave only one isolate. Two strains of gliding bacteria were obtained from each DW and Vy/2 isolation medium, while one strain was obtained from the SAP2 medium. Gliding bacteria strains RPD001, RPD008 and RPD018 were identified as Flavobacterium anhuiense with 96, 82 and 96 % similarity, respectively. Strains RPD049 and RPD027 were identified as F. johnsoniae and Lysobacter brunescens, respectively, with similarity equal to 96 %. Only crude extract obtained from RPD001 inhibited growth of Listeria monocytogenes (MIC 150 µg/ml), Staphylococcus aureus (MIC 75 µg/ml) and Vibrio cholerae (MIC 300 µg/ml), but showed weak inhibitory effect on Salmonella typhimurium (MIC > 300 µg/ml). Gliding bacterium strain RPD008 should be considered to a novel genus separate from Flavobacterium due to its low similarity value. Crude extract produced by RPD001 showed potential for development as a broad antibiotic agent.

The synthesis of novel azole derivatives has been accomplished during chemical transformations of the 1-(2-methyl-5-nitrophenyl)-5-oxopyrrolidine-3-carbohydrazide. The structure of the synthesized compounds was determined by NMR and IR spectroscopies. Most of the synthesized compounds were screened for their antibacterial activity against S. aureus, L. monocytogenes, E. coli, and P. aeruginosa bacteria strains.
