MSN-50 is a Bax and Bak oligomerization inhibitor. MSN-50 efficiently inhibits liposome permeabilization, prevents genotoxic cell death and promotes neuroprotection[1][2].
MSN-50 (0~10 uM) inhibits dye release from liposomes in a concentration-dependent fashion. MSN-50 (0~40 uM) inhibits tBid/Bax-mediated MOMP (mitochondrial outer membrane permeabilization) in a concentration-dependent manner and shows concentration-dependent inhibition of Bak-mediated MOMP. MSN-50 inhibits both Bax and Bak after activation by either cBid or Bim. MSN-50 (5 μM; BMK cells) inhibits apoptosis induced by actinomycin D and staurosporin (STS)[1][2].

Mesoporous silica nanoparticles loaded with capsaicin and their oxidation resistance in meat preservation
Food Chem 2021 May 15;344:128737.PMID:33277125DOI:10.1016/j.foodchem.2020.128737
In this work, capsaicin (CAP) was loaded into mesoporous silica nanoparticles (MSNs) with grain diameters of 50 nm, 100 nm and 400 nm by free diffusion to obtain the support materials Cap@MSN-50, Cap@MSN-100 and Cap@MSN-400, respectively. The loading capacity was separately calculated as 854.77, 713.86 and 649.09 (mg/g Cap/MSN) by ultraviolet spectrophotometry. An IFFM-E flow injection chemiluminescent analyzer was used for the slow-release experiment, which demonstrated that the MSN release of CAP proceeded with a slow-release effect and MSNs with a smaller grain diameter had a higher rate of slow release and stronger oxidation resistance. The prepared materials were used to maintain the freshness of ground beef by modified atmosphere packaging. After more than 5 days of storage, Cap@MSN-50 retained better oxidation resistance than CAP. The results show that loading CAP into mesoporous nanomaterials has the potential application value for long-term preservation and oxidation prevention of some foods.
