  2024-05-29

  

  Placental cells also express P450 aromatase (CYP19A1, encoded by CYP19A1). In the placenta, this enzyme requires an external source of androgens, provided by the adrenal gland of the fetus, to form estrogen. The fetal adrenal gland produces dehydroepiandrosterone (DHEA) [9] and, in the placenta, it

  For the first series we decided to verify the effects induced, on the ALR2 inhibitory properties, of an additional steric hindrance on the carbon in α position with respect to the carboxylic group, by introducing a methyl group (R2=Me). Therefore, we synthesized a series of new α-alanine derivatives

  2024-05-28

  

  The biology of the A2BR is complex and needs to be considered contextually as the expression and effect of receptor engagement varies according to time post hypoxic injury, cell type and downstream signaling pathway. For example, A2BR expression is dynamic - low under basal and increasing under isch

  2024-05-28

  

  The physiological effect of adenosine is now considered a new direction in halting the progression of organ damage in cardiovascular disease [24], [25], [26]. Adenosine has diverse functions, depending on its interaction with different receptor subtypes: A1, A2A, A2B, and A3[24], [25], [26]. Stimula

  2024-05-28

  

  Given the powerful and ubiquitous nature of adenosine action within the CNS, basal levels of extracellular adenosine are carefully regulated and are estimated to be in the region of 30–300 nM (Fredholm et al., 2001). The two main pathways for the control of extracellular adenosine involve phosphoryl

  During the course of our ACK1 inhibitor program, a high-throughput screening (HTS) campaign of our internal sample collection was conducted. A series of -aryl pyrimidine-5-carboxamides of the general structure () was identified. Earlier studies of the structure–activity relationship (SAR) of ident

  Introduction Dementia is a common disease in the elderly, and a significant source of disability, healthcare spending, and long-term care admissions. There is evidence to suggest that testosterone plays a role in cognitive functioning, and lower serum levels correlate with higher amyloid deposits (

  A rational approach for the design of new steroid compounds as possible competitive inhibitors of CYP17 include chemical modification at C17 of the enzyme's natural substrates, pregnenolone (1) and progesterone (2), introducing groups with moderate to strong dipole properties at C20, such as oxime a

  2024-05-28

  

  MafB, a member of the Maf protein family, is essential for terminal differentiation of macrophages (Kelly et al., 2000). The phagocytic activity of polystyrene beads was found to be enhanced in CVT 10216 with exogenous expression of MafB (Tillmanns et al., 2007). However, in alveolar macrophages of

  Matthew et al. synthesized and carried out SAR studies of imidazo-[1,2-a]-pyrazine as Aurora kinase inhibitors with enhanced kinase selectivity and found that NSC 66811 39 showed optimal potency on Aurora-A and Aurora-B with IC50 value of 4 nM and 13 nM while on phosphorylation histone H3 (pHH3), E

  In our H+, K+-ATPase assay (Fig. 1 and Supplementary Fig. 1), myricetin (IC50 = 0.58μM) was more potent than acid-activated omeprazole (IC50 = 1.50μM). In contrast, in oral administration in mice (Fig. 3), omeprazole (20mg/kg) more effectively inhibited gastric Pentamidine secretion compared to myr

  A high-throughput screening campaign led to the discovery of the first series of both potent and selective ATR kinase inhibitors by Vertex Pharmaceuticals (Charrier et al., 2011). One of these compounds, VE-821, was shown to be a potent ATP-competitive inhibitor of ATR with minimal cross-reactivity

  Furthermore, because most of foods and beverages have been consumed after processing, researchers have focused on the effects of processing (e.g. blanching, cooking, drying, cooling, freezing, high-pressure treatment, pulsed electric field) on total antioxidant capacity of foods.
