Meisoindigo Acts as a Molecular Glue to Target PKMYT1 for Degradation in Chronic Myeloid Leukemia Therapy

open access: yesAdvanced Science, EarlyView.
Meisoindigo targets PKMYT1 for degradation by acting as a molecular glue that enhances PKMYT1‐TRIM25 interaction, leading to K48‐linked ubiquitination and subsequent proteasomal degradation, thereby exerting therapeutic effects in chronic myeloid leukemia.

A simple, efficient and rapid screening technique for differentiating nitrile hydratase and nitrilase producing bacteria

open access: yesBiotechnology Reports, 2019
Nitrile hydrolyzing enzymes catalyze the hydration of nitrile compounds to corresponding amides and acids. Bacteria, isolated from soil samples were screened for nitrile hydrolyzing enzymes by simple dye based 96 well plate and nesslerization method ...

A General Strategy for C(sp3)─H Bond Etherification via Quinoline Derivative‐Mediated Electrolysis

open access: yesAdvanced Science, EarlyView.
A quinoline‐based mediator is introduced for the electrochemical etherification of C(sp3)─H bonds, enabling the process with minimal dependence on substrate electronic properties. The reaction demonstrates compatibility with various C─H bonds, including tertiary benzylic C─H bonds and unactivated C(sp3)─H bonds.

LncRNA‐MEG3 Regulates Muscle Mass and Metabolic Homeostasis by Facilitating SUZ12 Liquid–Liquid Phase Separation

open access: yesAdvanced Science, EarlyView.
This study has identified lncRNA‐MEG3 as a key regulator of muscle mass, promoting slow‐twitch muscle fibers and preventing muscle atrophy. By stabilizing the SUZ12/PRC2 complex through liquid–liquid phase separation (LLPS), lncRNA‐MEG3 influences mitochondrial function and lipid metabolism.

Momentum Transfer Rate Constants for Collision of Cl-with Trans-Dichloroethylene and Para-Difluorobenzene [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used

Identification and Characterization of Three Epithiospecifier Protein Isoforms in Brassica oleracea

open access: yesFrontiers in Plant Science, 2019
Glucosinolates present in Brassicaceae play a major role in herbivory defense. Upon tissue disruption, glucosinolates come into contact with myrosinase, which initiates their breakdown to biologically active compounds.
