Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
Human peripheral blood monocytes 50 µM 0.5-4 hours ISO-1 profoundly inhibited LPS-induced TNF-α, CXCL8, and IL-1β release. When the interval between ISO-1 and LPS was 4 hr, IL-1β release was no longer inhibited, while TNF-α and CXCL8 release remained blocked. Immunology. 2008 Sep;125(1):101-10.
PC12 cells 7 µM 1 hour To evaluate the protective effect of ISO-1 against AGEs and Aβ1-40-induced PC12 cell injury, results showed that ISO-1 significantly improved the survival rate and reduced the expression of inflammatory mediators in the AD cell model. Mol Med Rep. 2019 Sep;20(3):2135-2142.
Human cartilage end plate chondrocytes 100 µg/mL 12 hours To evaluate the inhibitory effect of ISO-1 on MIF-induced inflammatory cytokine secretion, results showed that ISO-1 significantly downregulated the secretion of IL-6, IL-8, and PGE2. Clin Orthop Relat Res. 2014 Jun;472(6):1943-54.
Human monocyte-derived macrophages (MDM) 50 µM 1-24 hours ISO-1 had no significant effect on LPS-induced TNF-α and CXCL8 release in MDM. Immunology. 2008 Sep;125(1):101-10.
Human neuroblastoma cells SH-SY5Y 50 µM 24 hours To evaluate the effect of ISO-1 on cell survival and expression of apoptosis-related proteins in an oxygen-glucose deprivation/reperfusion (OGD/R) model. Results showed that compared to the OGD/R group, the ISO-1 group had significantly lower cell survival rates, increased expression of pro-apoptotic proteins Caspase-3 and Bax, and decreased expression of anti-apoptotic protein Bcl2 and neuronal marker MAP2. Neural Regen Res. 2020 Aug;15(8):1483-1489.
NRK-52E cells 50 µM 24 hours To evaluate the inhibitory effect of ISO-1 on AA-induced EMT and matrix deposition. The results showed that ISO-1 significantly decreased the levels of MIF in AA-treated TECs and reversed AA-induced upregulation of α-SMA expression and downregulation of E-cadherin expression. Furthermore, ISO-1 also reduced the expression of type III collagen and the levels of TGF-β1. Mediators Inflamm. 2016;2016:2174682.
MKN-45 cells 100 nMol 24 hours To investigate the effect of ISO-1 on LPS-induced MKN-45 cell proliferation, results showed that ISO-1 significantly inhibited LPS-induced cell proliferation. World J Gastroenterol. 2012 May 14;18(18):2253-61.
Hippocampal neurons 10 µM and 100 µM 48 hours To investigate the effect of ISO-1 on neurite outgrowth. Results showed that 10 μM and 100 μM ISO-1 significantly reduced the length of the longest neurites and the number of terminal tips of neurites in cultured neurons. Front Mol Neurosci. 2020 Aug 12;13:147.
Gallbladder cancer cell lines (TGBC24TKB, OCUG-1, NOZ, GB-d1) 0 to 500 µM 48 hours To evaluate the effect of ISO-1 and 4-IPP on the viability of gallbladder cancer cells, results showed both inhibitors significantly reduced cell viability. BMC Cancer. 2015 Nov 4;15:843.
PlMDCK cells 10 µM and 100 µM 5 days To test the effect of the MIF inhibitor ISO-1 on in vitro cyst growth, results showed that ISO-1 significantly inhibited cAMP-dependent cyst enlargement in a dose-dependent manner. J Mol Med (Berl). 2020 Nov;98(11):1547-1559.
THP-1 monocytic cell line 50 µM Preliminary data suggested that the effects of ISO-1 might be transient. Immunology. 2008 Sep;125(1):101-10.
Hs 683 cells 100 or 1000 µM ISO-1 could restore dexamethasone sensitivity in these cells J Biol Chem. 2009 Nov 20;284(47):32483-92.
U373 MG cells 100 or 1000 µM ISO-1 could restore dexamethasone sensitivity in these cells J Biol Chem. 2009 Nov 20;284(47):32483-92.

C57BL/6 mice ICV-STZ-induced sporadic AD model Intraperitoneal injection 20 mg/kg Daily for 4 weeks To evaluate the effect of ISO-1 on ICV-STZ-induced cognitive impairment. Results showed that ISO-1 significantly improved STZ-induced impairment in contextual memory performance. Mol Med. 2020 Apr 17;26(1):34
B10.RIII mice Experimental autoimmune uveitis (EAU) model Intraperitoneal injection 20 mg/kg Once daily for 14 days ISO-1 attenuated intraocular inflammation and inhibited the differentiation of Th1 and Th17 in EAU mice. Clin Exp Immunol. 2016 Feb;183(2):280-93
C57BL/6 mice OVA-sensitized/challenged murine model of chronic asthma Intraperitoneal injection 35 mg/kg 0.5 h before each OVA challenge, 3 days per week for 6 weeks ISO-1 significantly mitigated all symptoms caused by OVA treatment, including airway inflammation, airway wall thickening, airway smooth muscle hypertrophy, subepithelial fibrosis, and goblet cell hyperplasia. Additionally, ISO-1 significantly reduced TGF-β1 mRNA levels in pulmonary tissue and its protein level in bronchial alveolar lavage fluid supernatants. Mol Med. 2010 Sep-Oct;16(9-10):400-8
Mice Polycystic kidney disease Mice model Intraperitoneal injection 40 mg/kg 5 days per week for 12 weeks To test the effect of ICA on MIF and ABCA1 expression, results showed that ICA significantly increased MIF and ABCA1 expression, while deletion of HIF-1α prevented this upregulation.

Kunming mice Developing hippocampus Intraperitoneal injection 7 mg/kg Once daily for 9 consecutive days To investigate the effect of ISO-1 on hippocampal cell proliferation.
