A facile threecomponent solid phase synthesis of steroidal Aring fused pyrimidines under microwave irradiation [PDF]

open access: yes
The preparation of ringA fused pyrimidines at the steroidal 2,3position is herein described. The novel steroidal pyrimidines were prepared from the solid phase threecomponent reaction of 2hydroxymethylene3keto steroids, arylaldehydes and ammonium ...

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

open access: yesIntegrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

open access: yesIntegrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Efficacy and Safety of Anal High‐Grade Squamous Intraepithelial Lesion Treatment Modalities: A Systematic Review

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Background There is compelling evidence that treating high‐grade squamous intraepithelial lesions (HSIL), the anal squamous cell cancer (ASCC) precursor, reduces the risk of developing ASCC. Using high‐resolution anoscopy (HRA), surgical excision, ablative and topical therapies are widely used to treat HSIL.

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Polarized effects of adenosine on blood–brain barrier integrity: Tightening from the luminal and opening from the abluminal side

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Adenosine as a signalling molecule modifies blood–brain barrier (BBB) tightness in pathological conditions. Our aim was to investigate the direct and polarized effects of adenosine on the BBB using co‐culture and in vivo models. Experimental Approach The expression of adenosine receptors was measured by qRT‐PCR.

MAP17 Enhances Chemoresistance and Tumorigenicity of Glioblastoma‐Initiating Cells via the Canonical NF‐кB Pathway

open access: yesCancer Science, EarlyView.
MAP 17 is identified as highly expressed in TMZ‐resistant glioblastoma‐initiating cells (GICs). MAP17 enhances GIC proliferation, TMZ resistance, and tumorigenicity through NF‐κB/RELA‐dependent BCL2 upregulation. ABSTRACT Glioblastoma (GBM) is the most common malignant brain tumor in adults.

Aspartate Transporter SLC1A3 Promotes Colorectal Cancer via MDM2‐p53 Pathway and M2 Macrophage Polarization

open access: yesCancer Science, EarlyView.
SLC1A3 promotes colorectal cancer progression by transporting extracellular aspartate into tumor cells, thereby activating the PKC/MDM2/p53 pathway to enhance proliferation. Reduced extracellular aspartate, combined with p53‐dependent suppression of CSF2 and IL17C, drives M2 macrophage polarization via immune modulation, macrophage recruitment, and M2 ...
