As anandamide (N-arachidonoylethanolamine, AEA) shows neuroprotective effects, the inhibition of its degradative enzyme, fatty acid amide hydrolase (FAAH) has been considered as a hopeful avenue for the treatment of neurodegenerative diseases, like Alzhei

Idiopathic pulmonary fibrosis (IPF) is a serious and fatal lung disease, with a median survival of only 3–5 years from diagnosis. Janus kinase 3 (JAK3) has a well-established role in the pathogenesis of various autoimmune diseases, including rheumatoid arthritis (RA) and autoimmune-related pulmonary fibrosis. In this study, through the use of a conformationally-constrained design strategy, a series of thieno[3,2-d]pyrimidines were synthesized as potent JAK3 inhibitors for the treatment of IPF. Among them, the most potent JAK3 inhibitor, namely 8e (IC50 = 1.38 nM), significantly reduced the degree of airsacculitis and fibrosis according to hematoxylin-eosin (HE) staining assay for the lung tissue in the bleomycin (BLM)-induced pulmonary fibrosis mouse model. The clear reduction of the lung collagen deposition by the determination of Masson and hydroxyproline (HYP) content also demonstrated its efficacy in the treatment of fibrosis. In addition, 8e also reduced the expression of the inflammatory markers IL-6, IL-17A, TNF-α and malondialdehyde (MDA) in lung tissue, which indicated its higher anti-inflammatory activity compared with that of the reference agents (nintedanib and gefitinib). Furthermore, it possessed low cytotoxicity against normal human bronchial epithelia (HBE) cells (IC50 > 39.0 μM) and C57BL mice. All these evaluated biological properties suggest that 8e may be a potential JAK3 inhibitor for the treatment of IPF.

Bruton's tyrosine kinase (BTK) has emerged as an attractive target related to B-lymphocytes dysfunctions, especially hematologic malignancies and autoimmune diseases. In our study, a series of diphenylaminopyrimidine derivatives bearing dithiocarbamate moieties were designed and synthesized as novel BTK inhibitors for treatment of B-cell lymphoma. Among all these compounds, 30ab (IC50 = 1.15 ± 0.19 nM) displays similar or more potent inhibitory activity against BTK than spebrutinib (IC50 = 2.12 ± 0.32 nM) and FDA approved drug ibrutinib (IC50 = 3.89 ± 0.57 nM), which is attributed to close binding of 30ab with BTK predicted by molecular docking. In particular, 30ab exhibits enhanced anti-proliferative activity against B-lymphoma cell lines at the IC50 concentration of 0.357 ± 0.02 μM (Ramos) and 0.706 ± 0.05 μM (Raji), respectively, almost 10-fold better than ibrutinib and spebrutinib. In addition, 30ab displays stronger selectivity on B-cell lymphoma over other cancer cell lines than spebrutinib. Furthermore, 30ab efficiently blocks BTK downstream pathways and results in apoptosis of cancer cells. In vivo xenograft model evaluation demonstrates the significant efficacy and broad safety margin of 30ab in treatment of B-cell lymphoma. We propose that compound 30ab is a candidate for further study and development based on our current findings.
