Results: Results showed that Nio-Curc had a mean particle size of 284.93 ± 14.27 nm, zeta potential of -46.93 and encapsulation efficacy of 99.62%, which demonstrates optimized physicochemical characteristics. Curcumin release in vitro could be sustained for up to 24 h. Additionally, Nio-Curc effectively reduced mRNA transcript expression of pro-inflammatory markers; IL-6, IL-8, IL-1β and TNF-a in immortalized human airway basal cell line (BCi-NS1.1). Conclusion: In this study, we have demonstrated that Nio-Curc mitigated the mRNA expression of pro-inflammatory markers in an in vitro study, which could be applied to treatment of asthma with further studies.]]> Tue 03 May 2022 12:13:38 AEST ]]> Synthesis, molecular modeling and biological activity of methyl and thiomethyl substituted pyrimidines as corticotropin releasing hormone type 1 antagonists https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:1663 50 : 1 noted. All analogues were screened for their ability to interact with CRH₁ and CRH₂ receptors. In all instances only poor agonistic and/or antagonistic behaviour was noted at CRH₂. However, several compounds were potent and selective CRH₁ antagonists, most notably 13a Ki = 39nM. Additionally we have utilized these data and that recently reported by others to refine our original CRH₁ pharmacophore.]]> Sat 24 Mar 2018 08:30:27 AEDT ]]>
