Summary: Two strains of Actinobacteria, CRXT-Y-14(T) and CRXT-G-22(T), isolated from healthy leaves and seeds of Xanthium sibiricum, display characteristic morphological features consistent with the Streptomyces genus. Phylogenetic analyses suggest CRXT-Y-14(T) may represent a novel species, while CRXT-G-22(T) is closely related to Streptomyces acidiscabies. Proper classification as Streptomyces xanthii and Streptomyces roseirectus is proposed based on genetic and phenotypic characteristics.

Summary: In this study, a new method for amide bond formation using a compound called 2-methyl-3-(thiazol-2-ylcarbamoyl)phenylacetate (MTP) was performed. The MTP compound was characterized using various spectral techniques and its crystal structure was analyzed. Molecular docking studies and druglikeness assay were conducted to evaluate the potential drug characteristics of MTP. The results showed that MTP exhibited strong antibacterial and antifungal activities. These findings suggest that compounds with a thiazole ring, including MTP, could be utilized as antibacterial agents in the future.
