Stereoselective rhodium-catalyzed reaction of allenes with organoboronic reagents for diversified branched 1,3-alkadienes

open access: yesNature Communications
The terminal isoprene unit, as the simplest branched 1,3-diene unit, exists in a wide range of natural products and bioactive molecules. Herein, we report a stereoselective rhodium-catalyzed reaction of allenes with readily available methyl pinacol ...

MiR‐195 and miR‐497 suppress tumorigenesis in lung cancer by inhibiting SMURF2‐induced TGF‐β receptor I ubiquitination

open access: yesMolecular Oncology, 2019
SMURF2 is a member of the HECT family of E3 ubiquitin ligases that have important roles as a negative regulator of transforming growth factor‐β (TGF‐β) signaling through ubiquitin‐mediated degradation of TGF‐β receptor I.

Thermostable neutral metalloprotease from Geobacillus sp. EA1 does not share thermolysin's preference for substrates with leucine at the P1′ position

open access: yesFEBS Letters, EarlyView.
Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...

Circularly polarized luminescence with high dissymmetry factors for achiral organic molecules in solutions

open access: yesNature Communications
Circularly polarized luminescence (CPL) in solution offers several advantages. However, it remains challenging for organic molecules to achieve circularly polarized luminescence with high dissymmetry factor (g lum) in solution. Herein, a general strategy

Complexation of 2,6-helic[6]arene and its derivatives with 1,1′-dimethyl-4,4′-bipyridinium salts and protonated 4,4'-bipyridinium salts: an acid–base controllable complexation

open access: yesBeilstein Journal of Organic Chemistry, 2019
2,6-Helic[6]arene and its derivatives were synthesized, and their complexation with 1,1′-dimethyl-4,4′-bipyridinium and protonated 4,4'-bipyridinium salts were investigated in detail. It was found that the helic[6]arene and its derivatives could all form

OLIGOSACCHARIDES AND MOLECULAR RECOGNITION [PDF]

open access: yes, 2014
Carbohydrates have been established as the most abundant ? and arguably the most structural diverse ? organic molecules found in nature. They are chiral molecules readily available in nature in a variety of diastereomeric forms. Their conformational rigidity provides a well defined three-dimensional spatial arrangement of substituents with various ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Polymer adsorption onto random planar surfaces: Interplay of polymer and surface correlation

open access: yes, 2005
We study the adsorption of homogeneous or heterogeneous polymers onto heterogeneous planar surfaces with exponentially decaying site-site correlations, using a variational reference system approach.
