Isoimperatorin is a naturally occurring furocoumarin and is being considered as a potential chemoprevention. Only one crystal form of isoimperatorin (Form I) was reported during previous research so that an investigation of polymorphism of isoimperatorin was successfully undertaken. A new polymorph of isoimperatorin was discovered through comprehensive polymorph screening experiments. Their structures were elucidated by single-crystal structure analysis and extensively characterized by XRPD, DSC, FT-IR, and SEM. The results showed that the crystal structure and thermal properties of the new polymorph (Form II) were significantly different from those of Form I. Thermodynamic stability and phase transformation were also discussed in detail.

Lipodystrophic patients have an adipose tissue triglyceride storage defect that causes ectopic lipid accumulation, leading to severe insulin resistance. The present study investigated the potential role of isoimperatorin on 3T3-L1 adipocyte differentiation. mRNA and protein levels of differentiation- and lipid accumulation-associated genes, as well as the adipogenesis-related signaling pathway were analyzed in control and isoimperatorin-treated differentiated 3T3-L1 adipocytes using reverse transcription-quantitative PCR and western blot analysis. Results determined that isoimperatorin promoted 3T3-L1 fibroblast adipogenesis in a dose-dependent manner compared with standard differentiation inducers. Isoimperatorin significantly increased mRNA and protein expression of the crucial adipogenic transcription factors peroxisome proliferator activated receptor-γ (PPARγ) and CCAAT enhancer binding protein-α (C/EBPα). mRNA expression of the downstream adipogenesis-related genes sterol regulatory element-binding transcription factor 1c, adipocyte protein 2, fatty acid synthase, adiponectin and diacylglycerol O-acyltransferase 2 were also significantly increased following isoimperatorin treatment. The underlying mechanism likely involved activation of the Akt signaling pathway. Taken together, the present findings indicated that isoimperatorin may alter PPARγ and C/EBPα expression via the Akt signaling pathway, resulting in promotion of adipogenesis. The results highlighted the potential use of isoimperatorin as a therapeutic agent for preventing diabetes.

The present study was designed to investigate the antiproliferative activity of isoimperatorin against SGC-7901 cells and to examine the possible mechanisms. The antiproliferative activity of isoimperatorin against SGC-7901 cells was evaluated using an MTT assay, and the mechanisms were investigated using flow cytometry and western blot assays, which were used to determine the apoptotic rate and expression levels of mitochondria-mediated apoptosis-associated proteins, including Survivin, myeloid leukemia cell-1 (Mcl-1), B cell lymphoma-extra large (Bcl-xl), B cell lymphoma 2 (Bcl-2), second mitochondria-derived activator of caspase (Smac), Bcl-2-associated X factor (Bax), cleaved (c)-caspase-3 and c-caspase-9 in SGC-7901 cells. Additionally, a xenograft assay was used to confirm whether isoimperatorin had an inhibitory effect on SGC-7901 cell-induced tumors in vivo. The results of the MTT assay suggested that isoimperatorin significantly inhibited the proliferation of SGC-7901 cells in a dose- and time-dependent manner, and the half maximal inhibitory concentration was 18.75 µg/ml. The results of the flow cytometric analysis indicated that, following treatment with isoimperatorin, the apoptotic rate of SGC-7901 cells was significantly increased, compared with that of cells in the control group. The results of the western blot analysis indicated that, following treatment with isoimperatorin, the expression levels of the pro-apoptotic proteins, Bax, c-caspase-3 and c-caspase-9, were significantly increased and the expression levels of the anti-apoptotic proteins, Survivin and Bcl-2, were significantly reduced, compared with the control group. No alterations in expression were found in the other apoptosis-associated proteins, including Mcl-1, Bcl-xl and Smac. The results of the xenograft assay indicated that isoimperatorin significantly inhibited the growth of SGC-7901 cell-induced tumor in vivo by increasing the expression levels of pro-apoptotic proteins (Bax, c-caspase-3 and c-caspase-9) and reducing the expression levels of anti-apoptotic proteins (Survivin and Bcl-2) without adverse effects on the increasing body weight of nude mice. In conclusion, the present study revealed that isoimperatorin may be able to induce the apoptosis of SGC-7901 cells in vitro and in vivo by regulating the expression levels of mitochondria-mediated apoptosis-associated proteins.
