Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

BMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

Possible Enantioseparation of Racemic Ribose on Chiral Surface Formed by Adsorption of Nucleobases

Life
The paper proposes a putative prebiotic scenario leading to homochirality in the RNA world. In this scenario, racemic ribose, the only chiral moiety in RNA, was enantioseparated (in its pyranose form) on a chiral surface formed by the adsorption of ...

Prospects for non-immunological molecular therapeutics in melanoma [PDF]

, 2010
In 2006 there were 60,000 new cases of cutaneous melanoma in the European Union and 13,000 deaths (www.europeancancerleagues.org). Currently available systemic treatment options for metastatic melanoma, including both cytotoxic and immunologic therapies,

Engineering Bisubstrates to Target m6Am RNA Methyltransferases: Synthesis and Computational Studies

Chemistry – A European Journal, EarlyView.
Use of the convertible nucleoside approach to synthesize m6Am RNA methyltransferase bisubstrates. This methodology allows for the introduction of modifications on the SAM analog moiety and the RNA substrate part, including the introduction of a cap analog by click chemistry.

DNA damage by ribose: inhibition at high ribose concentrations.

Indian journal of biochemistry & biophysics, 2010
Nucleobases and DNA react non-enzymatically with sugars, and generate DNA-advanced glycation end products (DNA-AGEs). Incubation of plasmid pBr322 with ribose for 3-7 days caused the transformation of the supercoiled plasmid to the open circular and linear forms.

ProTides for Antiviral Activity Beyond Liver Cells

Chemistry – A European Journal, EarlyView.
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

Is a Clinical Trial With a Non‐Bioequivalent Batch Necessary? The Critical Role of Intrasubject Variability in Olaparib Formulation Bridging by PBPK

Clinical Pharmacology &Therapeutics, EarlyView.
Although physiologically based pharmacokinetic (PBPK) modeling is increasingly being used to support oral drug formulation bridging, the acceptance by regulatory agencies is low. One of the primary concerns is the absence of clinical pharmacokinetic (PK) data from a non‐bioequivalent (non‐BE) batch during model validation.

Nucleolar-nucleoplasmic shuttling of TARG1 and its control by DNA damage-induced poly-ADP-ribosylation and by nucleolar transcription

Scientific Reports, 2018
Macrodomains are conserved protein folds associated with ADP-ribose binding and turnover. ADP-ribosylation is a posttranslational modification catalyzed primarily by ARTD (aka PARP) enzymes in cells.
