Mycobacterium marinum infection in Drosophila melanogaster for antimycobacterial activity assessment
Heptane-extractable fractions (HEF) prepared from immune-activated macrophages (IA-M) of tubercle bacilli or bovine gamma globulin-sensitized and -challenged guinea pigs inhibited the growth of tubercle bacilli whereas HEF of normal macrophages exerted no antibacterial activity. In distinction to the strong antibacterial activity of HEF of IA-M, HEF of immune macrophages exerted weak or no anti...
The present study was aimed at evaluating the antibacterial activity of mulinane and azorellane diterpenes isolated from the Andean plants Azorella compacta and A. trifoliolata and semisynthetic derivatives against reference and multidrug-resistant strains. The results revealed that the semisynthetic compound 7-acetoxy-mulin-9,12-diene (5) exhibited antibacterial activity against reference and ...
A racemic, prenylated polyketide dimer, oxazinin A (1), was isolated from a novel filamentous fungus in the class Eurotiomycetes, and its structure was elucidated spectroscopically. The pentacyclic structure of oxazinin A (1) is a unique combination of benzoxazine, isoquinoline, and a pyran ring. Oxazinin A (1) exhibited antimycobacterial activity and modestly antagonized transient receptor pot...
A number of antimycobacterial agents were evaluated with respect to their bacteriostatic activity (growth inhibition) versus the bactericidal activity against a clinical isolate of Mycobacterium avium (Mycobacterium avium complex [MAC] strain 101) in relation to the time of exposure and the growth phase of the mycobacteria. In terms of growth inhibition the MAC in the active phase of growth was...
