Butadiene-imide 1 (T-686) derivatives were synthesized and evaluated for their inhibitory activity against PAI-1 production and their ADMET (DMPK and toxicology) profiles. Among these derivatives, compound 15k (T-2639) showed good antithrombotic activity in two rat thrombosis models without affecting bleeding time, indicating reduction of haemorrhagic risk. We also describe in this report a practical synthesis of 15k suitable for scale-up using Z,E-selective Stobbe condensation.

Background/purpose: Revascularization procedures are used over apexification to treat teeth with necrotic pulp tissues and incomplete root formation. Clinically, inducing proliferation, migration, matrix deposition, and differentiation of stem cells from apical papilla (SCAPs) are critical for pulp regeneration. The study aimed to elucidate the impact of bone morphogenetic protein-4 (BMP-4) on plasminogen activation molecules and the osteogenic/odontogenic differentiation of SCAPs, as well as understand the related signaling mechanisms.

A role for the plasminogen activator (PA) system has been postulated in mammalian gonads, considering the complex process of morphogenesis these organs undergo during their development. Our results show that mouse Sertoli cells under basal conditions produce both types of PA, tissue-type PA (tPA) and urokinase-type PA (uPA), and hormonal treatments increase the production of both enzymes. The increased enzyme secretion does not correlate with a parallel increase in their mRNAs.

Circadian misalignment, due to shiftwork and/or individual chronotype and/or social jetlag (SJL), quantified as the difference between internal and social timing, may contribute to cardiovascular disease. Markers of endothelial dysfunction and activation of the coagulation system may predict cardiovascular pathology. The present study aim was to investigate the effects of shift work, SJL, and chronotype on endothelial function and coagulation parameters.

Trauma-induced coagulopathy (TIC) is characterized by dynamic changes in fibrinolysis, which can significantly impact patient outcomes. These changes typically manifest in two phases: hyperfibrinolysis followed by fibrinolysis suppression. In the early stages of TIC, there is often an overwhelming release of tissue plasminogen activator, which leads to excessive fibrinolysis.

Vitronectin (VTN) is an important extracellular matrix protein in tissue remodeling, but its role in COPD is unknown. We show that VTN regulates tissue remodeling through urokinase plasminogen activator (uPA) signaling pathway in COPD. In human COPD airways and bronchoepithelial cells and the airways of mice with cigarette smoke (CS)-induced experimental COPD, VTN protein was not changed, but downstream uPA signaling was altered (increased plasminogen activator inhibitor-1, uPAR) that induced collagen and airway remodeling.
