Have been intratendineously injected with collagenase [42]. The low solubility of piperine restricted the calculation on the IC50 worth. The usage of a self-emulsifying drug-delivery technique proved to enhance the solubility and oral bioavailability [43] and could represent a future remedy for the development of piperine as antivirulence agent. Each capsaicin and curcumin had IC50 values decrease than five . Capsaicin can be a natural occurring vanilloid that was previously shown to possess antimicrobial and antivirulence activities on Group A streptococci [44], though a different study revealed its antifungal and antiparasitic potential [45]. Moreover, curcumin was reported in a different study to exert antibiofilm, antiefflux and anticapsule activities on hypervirulent Klebsiella pneumoniae [46]. Capsaicin and curcumin share widespread structural attributes that could explain their inhibitory activity on ColA, for example the vanillyl functional group and the ketone moieties. A large number of clinical trials demonstrated that the administration of each capsaicin and curcumin is safe at therapeutical doses [47,48].Life 2022, 12,11 of5. Conclusions Capsaicin, 4 ,5-dihydroxyflavone, curcumin, dihydrorobinetin, palmatine chloride, biochanin A, two -hydroxychalcone, and juglone had been identified as promising collagenase inhibitors. Piperine, four ,5-dihydroxyflavone and capsaicin had IC50 values inside the nanomolar range. Our information indicate these molecules may be utilized against infections caused by multi-drug-resistant bacterial pathogens which express collagenase A.Supplementary Materials: The following supporting facts is often downloaded at: mdpi/article/10.3390/life12122114/s1, Figure S1: The inhibitory effect of two compounds on ColA soon after 30 min.
