Targeting InhA in drug-resistant Mycobacterium tuberculosis: potent antimycobacterial activity of diaryl ether dehydrozingerone derivatives.

Tuberculosis (TB) remains a major global threat, with 10 million new cases and 1.5 million deaths each year. In multidrug-resistant tuberculosis (MDR-TB), resistance is most commonly observed against isoniazid (INH) and rifampicin (RIF), the two frontline drugs.

Design and synthesis of betulinic acid-dithiocarbamate conjugates as potential antifungal agents against .

Diverse betulinic acid-dithiocarbamate conjugates were designed and synthesized a two-step reaction at room temperature. Among the fourteen dithiocarbamate analogs of betulinic acid, DTC2 demonstrated the best antifungal activity against , with a minimum inhibitory concentration (MIC) of 4 μg mL, achieving 99% fungicidal activity at the same concentration. These compounds were found to be ineffective against common Gram-negative and Gram-positive pathogens, suggesting their specificity to fungi.

Modulating sonic hedgehog (SHH) pathway to create a rapid CNS-TB model: Facilitating drug discovery.

Tuberculous meningitis, a severe complication of Mycobacterium tuberculosis (M. tb) infection, involves the dissemination of bacilli in the brain. This study explored the role of the sonic hedgehog (SHH) signaling pathway in regulating blood-brain barrier (BBB) integrity, M.

Antifungal Efficacy of Ultrashort β-Peptides against Species: Mechanistic Understanding and Therapeutic Implications.

Candidiasis, a condition spurred by the unchecked proliferation of species, poses a formidable global health threat, particularly in immunocompromised individuals. The emergence of drug-resistant strains complicates management strategies, necessitating novel therapeutic avenues. Antimicrobial peptides (AMPs) have garnered attention for their potent antifungal properties and broad-spectrum activity against species.

Synthesis, Characterization, and Antimicrobial Activity of Ultra-Short Cationic β-Peptides.

The development of new antibiotics is urgently required because of the rapidly growing resistance against conventional antibiotics. The antimicrobial peptides show potential as small antibiotic molecules. The stability of peptides is a primary concern for the use of peptides as drugs.

Stibonic acids and related stibonate-phosphonate clusters: Synthesis, characterization and bioactivity evaluation.

The reaction of 4-(azobenzene)phenylstibonic acid with t-butylphosphonic acid led to the isolation of the tetranuclear oxo-hydroxo antimony cluster of formulae [(4-azobenzene-CHSb)(OH)(BuPO)] (C1). The reaction of (p-t-butyl phenyl stibonic acid with phenyl phosphonic acid resulted in the isolation of complex with formulae [(p-t-BuCHSb)(O)(PhPO)(PhPOH)] (C2). Based upon the initial results from docking studies, parent stibonic acids, t-butyl-phenylstibonic acid, p-isopropylphenylstibonic acid, 4-azobenzenephenylstibonic acid, and the derived tetranuclear organoantimonate-phosphonate clusters were screened against different cancer cell lines, various Gram-positive and Gram-Negative bacteria and mycobacteria for possible bioactivity profile.
