General description
A cell-permeable tripeptide derivative containing an Arg-X-Arg motive that acts as a highly potent and reversible furin inhibitor (Ki = 16 pM). Also shown to inhibit several other pro-protein convertases, such as PC1/3, PC4, PAEC4, PC5/6 with almost similar potency, but does not affect PC2, PC7, and trypsin-like serine proteases in any significant manner. Acts as a very weak inhibitor of plasmin (Ki = 7.3 µM). Exhibits greater stability in cells. Shown to block hemagglutinin cleavage (40% at 1 µM) and fowl plague virus (FPV) viral propagation in a dose-dependent manner. Exhibits minimal toxicity even at high concentrations (25-50 µM) and protects human epidermoid carcinoma (HEp-2) cells from toxic effects of Shiga toxin.

Tumors are characterized by the presence of malignant and non-malignant cells, such as immune cells including macrophages, which are preponderant. Macrophages impact the efficacy of chemotherapy and may lead to drug resistance. In this context and based on our previous

Cartilage degradation is a hallmark of osteoarthritis (OA). Aggrecan, a major proteoglycan of articular cartilage extracellular matrix (ECM), is degraded by ADAMTS-5 resulting in the release of ARGS-G2 fragments to synovial fluid and circulation. The aim was to quantify ARGS-G2

Macrophages plasticity is a key feature in cancer progression. Neoplastic cells can alter their immune functions and orient them into a pro-tumoral phenotype. In this context, we developed a new therapeutic strategy to switch macrophages phenotype and reactivate their anti-tumoral

A threonine-to-Isoleucine (Thr52Ile) mutation within the pro-domain of the Sorcs1 gene was positionally cloned as the gene underlying a quantitative trait locus that affects fasting insulin levels in mice. In humans, genome-wide association studies and linkage studies have shown that
