Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Regulation of neutral ceramidase in glomerular messangial cells [PDF]

open access: yes, 2009
During the past several years, ceramide has emerged as an important second messenger triggering cell responses including proliferation, differentiation, growth arrest and apoptosis.

Cytotoxicity Profiling of Tenacibaculum Extracellular Products on Chinook Salmon (Oncorhynchus tshawytscha) Gill Cell Line, OTgill1PFR

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Tenacibaculosis is an important disease of marine fishes caused by bacteria of the genus Tenacibaculum. Pathogenic Tenacibaculum species or serotypes, including Tenacibaculum maritimum, T. dicentrarchi, T. finnmarkense and T. soleae, have been isolated from farmed Chinook salmon (Oncorhynchus tshawytscha) during disease outbreaks in Aotearoa ...

Data on cell survival, apoptosis, ceramide metabolism and oxidative stress in A-494 renal cell carcinoma cell line treated with hesperetin and hesperetin-7-O-acetate

open access: yesData in Brief, 2018
Ceramide pathway is a key regulator in cell proliferation and apoptosis and oxidative stress up-regulate ceramides. Acid ceramidase (ACDase), neutral sphingomyelinase (NSMase) and glucosylceramide synthase (GCS) are critical enzymatic systems in ceramide

Histone deacetylase inhibitors as venetoclax‐sensitising partners in acute myeloid leukaemia: Mechanisms, pharmacology and translational perspectives

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 21, Page 6261-6290, November 2026.
Abstract Venetoclax combined with hypomethylating agents has improved treatment for older or unfit patients with acute myeloid leukaemia (AML), but resistance and relapse remain common. This review analyses the rationale for combining venetoclax with inhibitors of histone deacetylase (HDAC).

Stimulation of Acid Ceramidase Activity by Saposin D

open access: yesArchives of Biochemistry and Biophysics, 1994
Ceramide is ubiquitously present in plasma membranes and plays a pivotal role in metabolism of sphingolipids. In addition, ceramide and its hydrolytic product, sphingosine, may have important roles as second messengers for cell function and survival. Ceramide is hydrolyzed by both acid and alkaline ceramidase. In this investigation, saposin D was found

Identification of Cystatin SA as a Novel Inhibitor of Acid Ceramidase [PDF]

open access: yesJournal of Biological Chemistry, 2011
Autoproteolytic cleavage of the inactive acid ceramidase (AC) precursor into the active heterodimer exposes a free cysteine residue, leading us to study whether AC could be regulated by one or more members of the cystatin family. Co-expression of the full-length AC and cystatin SA (cysSA) cDNAs led to significant reduction of AC activity in the ...

Modifying Acid Ceramidase Inhibitors to Encourage Cancer Cell Apoptosis

open access: yes, 2023
In 2020 alone 1.9 million new cases of cancer were diagnosed. This challenging disease has a multitude of treatments that all hope to cure the cancer completely without recurrence.

Acid ceramidase confers radioresistance to glioblastoma cells

open access: yesOncology Reports, 2017
Glioblastoma multiforme (GBM) is the most common primary, intracranial malignancy of the central nervous system. The standard treatment protocol, which involves surgical resection, and concurrent radiation with adjuvant temozolomide (TMZ), still imparts a grim prognosis.

The Sleeping Giant: Metabolism and Autophagy in the Generation and Survival of Dormant Polyploid Giant Cancer Cells

open access: yesMedComm, Volume 7, Issue 10, October 2026.
Polyploid giant cancer cells (PGCCs) arise in response to stress and play a critical role in therapy resistance and tumor dormancy. These cells can evade conventional treatments and later contribute to cancer relapse by generating progeny through nonmitotic, amitotic mechanisms.
