| Bioactivity | NP213 TFA is a rapidly acting, novel, first-in-class synthetic antimicrobial peptide (AMP), has anti-fungal activities. NP213 TFA targets the fungal cytoplasmic membrane and plays it role via membrane perturbation and disruption. NP213 TFA is effective and well-tolerated in resolving nail fungal infections[1][2]. | ||||||
| Invitro | NP213 (500-1000 μg/mL; 18 hours) increases the number of PI-stained T. rubrum NCPF0118 cells in samples. This results suggests that NP213 is fungicidal and the mechanisms of action involved membrane permeabilization[1].NP213 is against T. rubrum NCPF0118, shows different MIC values against T. rubrum NCPF0118, and the MICs varies depending on the source of the keratin. The MIC values are 16-32 mg/L, 125 mg/L, and 250 mg/L for NP213 in 1640 media containing human nail Keratin, human skin Keratin and Lamb’s wool Keratin, respectively[1].NP213 TFA (2-3 hours; 0-8 μg/ml) has great activity against clinically relevant yeast, including candida spp, Cryptococcus spp and Trichosporon spp. For all 122 yeast isolates, with the median MIC100 values of 1-2 µg/ml[3].
