Development of catalysts for asymmetric hydrogenation [PDF]

The application of tetradentate aminoalcohol ligands to the KOtBu-catalysed hydrogenation of benzophenone has been studied. Hydrogenation was found to proceed via a transfer hydrogenation process with the ligands acting as hydrogen donors.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

FEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

(NHC)Mn(I) complex catalyzed selective transfer hydrogenation of epoxides, azoarenes and nitroarenes utilizing ammonia borane [PDF]

Herein, we have reported an effective protocol for the regioselective transfer hydrogenation (TH) of epoxides by utilizing a phosphine-free bis-NHC-Mn(I) complex and ammonia borane. By employing this strategy, aromatic epoxides were selectively converted

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Transfer Hydrogenation and Transfer Hydrogenolysis. XVIII

Journal of Japan Oil Chemists' Society, 1978
In order to reduce methyl linoleate selectively, catalytic hydrogen transfer from eleven steroids, six terpenes, and an alkaloid was investigated at 140°C. In the hydrogenation with cholesterol and D-limonene, RuH2 (PPh3)4 was the most active catalyst and RhH (PPh3)4 was the next, but the latter showed higher selectivity to monoenes and less formation ...

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

From physisorption to chemisorption: Modulation of thermal conductance at metal/graphene/metal interfaces and the role of hydrogenation [PDF]

AIP Advances
Interfacial thermal conductance (ITC) in metal/graphene/metal contacts depends on interfacial bonding and can be tuned by surface functionalization. Building on prior evidence that single-sided hydrogenation strengthens coupling in Cu/graphene/Cu, we ...

Pd-Catalyzed Transfer Hydrogenation of Alkenes Using Tetrahydroxydiboron as the Sole Hydrogen Donor [PDF]

Tetrahydroxydiboron-mediated catalytic transfer hydrogenations have typically involved co-additives that, like tetrahydroxydiboron itself, are also H atom donors.
