Methicillin-resistant (MRSA) opportunistic infections are a major health burden. Decolonization of hospitalized patients with mupirocin (MUP) has reduced the incidence of infection but has led to MUP resistance. DIBI is a developmental-stage anti-infective agent that sequesters bacterial iron and bolsters innate host iron-withdrawal defenses. Clinical isolates possessing low, high, or no MUP resistance all had similarly high susceptibilities to DIBI. Intranasal DIBI reduced nares bacterial burdens in mice to the same extent as MUP. No resistance was found after exposure to DIBI.

Antimicrobial resistance (AMR) is one of the most challenging problems and is responsible for millions of deaths every year. We therefore urgently require new chemical entities with novel mechanisms of action. Phytocannabinoids have been adequately reported for the antimicrobial effect but not seriously pursued because of either stringent regulatory issues or poor drug-like properties.

Glucose homeostasis is closely regulated to maintain energy requirements of vital organs and skeletal muscle plays a crucial role in this process. Mustn1 is expressed during embryonic and postnatal skeletal muscle development and its function has been implicated in myogenic differentiation and myofusion. Whether Mustn1 plays a role in glucose homeostasis in anyway remains largely unknown.

The widespread utilization of mupirocin to treat methicillin-resistant (MRSA)-caused infectious diseases has led to the emergence of mupirocin-resistant (MuRSA), posing a serious global medical threat. In order to counteract MuRSA, we develop a d-α-tocopherol polyethylene glycol 1000 succinate (TPGS) modified mupirocin and silver complex (TPGS/Mup-Ag) to combat MuRSA. The surfactivity of TPGS endows Mup-Ag with a homogeneous and small particle size (∼16 nm), which significantly enhances bacterial internalization.

Disturbed endoplasmic reticulum (ER) stress response driven by the excessive lipid accumulation in the liver is a characteristic feature in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Restoring metabolic homeostasis by targeting ER stress is a potentially therapeutic strategy for NAFLD. Here we aim to identify novel proteins or pathways involved in regulating ER stress response and therapeutic targets for alleviating NAFLD.
