  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  The diagnosis of ICP is currently based on the presence of pruritus, raised fasting serum TBS levels above 10μmol/L, and/or elevated serum transaminases (in the absence of diseases that cause cholestasis or pruritus) as well as spontaneous relief of signs and symptoms within four to six weeks after

  Consistent with a damaging role for increased 12/15-LOX activity in stroke, systemic administration of the 12/15-LOX inhibitor, LB1, 2 h after permanent focal cerebral ischemia significantly reduced infarct size 24 h after the ischemia, and the treatment group demonstrated improved behavioral and he

  2024-08-27

  

  Further important evidence for G protein signaling on early endosomes has been subsequently obtained for the β2-adrenegic receptor using fluorescently-tagged conformation-sensitive nanobodies selectively recognizing the active receptor and Gs protein [43]. More recently, our group used a combinatio

  The approach of enzymatically converting an analyte and detecting it by the resulting small pH changes near the reduced graphene oxide (rGO) surface has successfully been pursued in case of urea (Piccinini et al., 2017). Furthermore, this work reported that electrostatic layer-by-layer (LbL) assembl

  It is reported that calpain-2 plays a critical role in BDNF-induced signaling and memory formation, and knockdown of calpain-2, but not calpain-1, completely suppresses BDNF-induced pathway activation and protein translation (Briz et al., 2013). BDNF prevents neuronal apoptosis or death (Ferrer et a

  Since the beginning of 1990s, more than 17,000 papers about physiological relevance of antioxidants have been published according to data from web of science. Based on the available literature, it seems that assessing the antioxidant potential of food by means of in vitro assays or solely epidemiolo

  Although the gene that encodes DHFR has been strongly conserved during evolution, subtle differences in the active sites of bacterial, human and parasite cytokine receptor have been exploited to develop DHFR inhibitors specific to particular pathogens 1, 3. For example, pyrimethamine and cycloguani

  Introduction Breast cancer is the most frequently occurring cancer in women, and despite the development of new therapies there has been little decline in the mortality rate over the past decade (Siegel et al., 2015). This is partly due to the genetic diversity of breast cancers, such that there

  It is worth mentioning that cordycepin, as an adenosine analogue, is structurally similar to adenosine. A previous study has shown that the anti-apoptotic effects of cordycepin are partially dependent on the activation of A1R [16], and cordycepin increases theta waves power density via nonspecific a

  ADORs accomplish a variety of physiological effects in different tissues. In neurons, ADORs regulate the release of neurotransmitters such as dopamine and glutamate (Ferré et al., 1992; Fredholm and Dunwiddie, 1988; Ginsborg and Hirst, 1972; Gonçalves et al., 2015; Quarta et al., 2004; Stella et al.
