Muscone is the main active monomer of traditional Chinese medicine musk. Previous studies have reported a variety of beneficial effects of muscone. However, the effects of muscone on chronic inflammation after myocardial infarction (MI) are rarely reported. This study evaluated the anti-inflammatory effects of muscone on myocardial infarction by establishing a MI model in mice. We found that muscone remarkably decreased the levels of inflammatory cytokines (IL-1β, TNF-α and IL-6), and ultimately improved cardiac function and survival rate. Furthermore, the main anti-inflammatory effect of muscone was alleviating cardiac macrophage-mediated inflammatory response in heart tissues after MI. Bone marrow-derived macrophages (BMDMs) induced with lipopolysaccharide (LPS) were used as an in vitro inflammation model to further clarify anti-inflammatory mechanisms of muscone. Muscone significantly downregulated the levels of LPS-induced inflammatory cytokines and inhibited NF-κB and NLRP3 inflammasome activation in BMDMs. Moreover, ROS and antioxidant indices in LPS-induced BMDMs were also ameliorated after muscone treatment. To sum up, our study found that muscone alleviated cardiac macrophage-mediated chronic inflammation by inhibiting NF-κB and NLRP3 inflammasome activation, thereby improving cardiac function in MI mice. Besides, the inhibitory effect of muscone on inflammation may be related to the scavenging of ROS. It is suggested that muscone may serve as a promising and effective drug for post-MI treatment.

Long-term alcohol abuse causes musculoskeletal disorders, among of which, alcohol-induced osteonecrosis of the femoral head (ONFH) is of concern due to its significant and severe complications. A variety of methods have been attempted to prevent alcohol-induced ONFH, and monomers extracted from Chinese herbs might benefit the disease profoundly. In the current study, muscone, the main ingredient of musk, was used to prevent alcohol-induced ONFH. In vitro, ethanol was used to affect the potential of osteogenesis and proliferation of human bone mesenchymal stem cells (hBMSCs), and beneficial role of muscone was investigated on hBMSCs. In vivo, following the establishment of alcohol-induced ONFH, muscone was employed to treat the diseased rats, which were analyzed by micro-CT scanning and a series of histologic staining. As a result, we found ethanol could significantly suppress osteogenic differentiation of hBMSCs, while muscone held the potential to promote ALP activity and mRNA expressions of COL1 and OCN under ethanol treatment. Meanwhile, imaging analysis revealed muscone could restore BV/TV ratio and bone mineral density of the necrotic femoral head, and the protective role of muscone on alcohol-induced ONFH was further confirmed by histologic examinations. Our study confirmed the protective effect of muscone against alcohol-induced ONFH both in vitro and in vivo. Therefore, muscone may be considered as a valuable therapeutic natural drug for alcohol-induced ONFH in humans.

Postmenopausal osteoporosis is caused by the deficiency of estrogen, which breaks bone homeostasis and induces levels of pro-inflammatory cytokines. Muscone is a potent anti-inflammatory agent and is used to treat bone fracture in traditional Chinese medicine. However, its anti-osteoclastogenic effects remain unclear. For in vitro study, morphology tests of osteoclastogenesis were firstly performed. And then, factors in RANK-induced NF-κB and MAPK pathways were examined by RT-PCR and Western blot, and the binding of TNF receptor-associated factor (TRAF)6 to RANK was inspected by coimmunoprecipitation and immunofluorescence staining. For in vivo experiments, C57BL/6 ovariectomized (OVX) mice were used for detection, including H&E staining, TRAP staining, and micro CT. As a result, muscone reduced OVX-induced bone loss in mice and osteoclast differentiation in vitro, by inhibiting TRAF6 binding to RANK, and then suppressed NF-κB and MAPK signaling pathways. The expression of the downstream biomarkers was finally inhibited, including NFATc1, CTR, TRAP, cathepsin K, and MMP-9. The inflammatory factors, TNF-a and IL-6, were also reduced by muscone. Taken together, muscone inhibited the binding of TRAF6 to RANK induced by RANKL, thus blocking NF-kB and MAPK pathways, and down-regulating related gene expression. Finally, muscone inhibited osteoclastogenesis and osteoclast function by blocking RANK-TRAF6 binding, as well as downstream signaling pathways in vitro. Muscone also reduced ovariectomy-induced bone loss in vivo.
