Several indole esters were tested as inhibitors of tyrosine kinase p60(c-Src). Compound (4) was found fairly active against the enzyme with IC50 = 1.34 microM. DOCK methodology was used to asses our inhibitors for their inhibitory potency against tyrosine kinase. The docking results showed that compounds (4), (25) and (26) were bound to the active site of the enzyme Lys 295 of p60(c-Src) tyrosine kinase. Both activity and docking studies showed a parallel result, with compound (4) having a better interaction with the enzyme active site and also greater activity than the other compounds, indicating a potential role as new lead inhibitor.

Fostamatinib had superior efficacy to a placebo and acceptable safety profiles for at least 1 year in a phase 3 study of Japanese patients with primary immune thrombocytopenia. Here, we report the 3-year safety and efficacy of fostamatinib in that study. Data from 33 patients who received at least one dose of fostamatinib were analyzed.

The overexpression of Human Epidermal Growth Factor Receptor 2 (HER2) protein is specifically related to tumor cell proliferation in breast cancers. Its presence in biological serum samples indicates presence or progression of cancer, becoming a promise biomarker. However, their detection needs a simple and high accuracy platform.

Deucravacitinib, an oral tyrosine kinase 2 inhibitor, is effective for psoriasis. However, long-term real-world effectiveness stratified by age and body mass index (BMI) has not been precisely examined. This study aimed to evaluate 52-week real-world effectiveness of deucravacitinib in psoriasis patients, stratified by age (≥65 years vs <65 years) and BMI (≥25 vs <25).

Infantile myofibromatosis (IM) comprises a wide clinical spectrum, ranging from solitary or multicentric lesions to generalized life-threatening forms. IM is mostly linked to germline or somatic heterozygous mutations in the PDGFRβ tyrosine kinase, encoded by the PDGFRB gene. Treatments for IM range from wait and see approach to systemic chemotherapy, according to the clinical context.

Section of Dermatology - Department of Clinical Medicine and Surgery, University of Naples Federico II, Naples, Italy.
Introduction: Bruton's tyrosine kinase (BTK) is a cytoplasmic signaling protein expressed across a variety of immune cells, terminally differentiated plasma cells, and natural killer cells. Due to the signal potential and targetable nature of BTK, the use of BTK inhibitors (BTKis) has been proposed for the management of several diseases. Currently, the use of BTKis is under investigations for several dermatological conditions such as pemphigus, systemic lupus erythematosus, hidradenitis suppurativa, atopic dermatitis, and chronic spontaneous urticaria (CSU).
