Enzyme-Triggered Transcytosis of Dendrimer-Drug Conjugate for Deep Penetration into Pancreatic Tumors.

ACS Nano, 2020
The dense fibrotic stroma in pancreatic ductal adenocarcinoma (PDA) resists drug diffusion into tumor and leads to unsatisfied prognosis. To address this problem, we demonstrate a dendrimer-camptothecin (CPT) conjugate that actively penetrates deep into ...

Domino Asymmetric Conjugate Addition–Conjugate Addition

Organic Letters, 2014
Enantioenriched Al-, Mg-, and Zn-enolates undergo electrophilic trapping by nitroolefins and vinylsulfones to afford 1,4-diketones and 2-(bis(phenylsulfonyl)ethyl)ketones in good yield and excellent diastereoselectivity. A one-pot preparation of indenes and enantiopure syntheses of tetrahydrobenzofurans, tetrahydrobenzopyrroles, and azulenes are ...

CONJUGATIVE TRANSPOSITION

Annual Review of Microbiology, 1995
Conjugative transposons are important determinants of antibiotic resistance, especially in gram-positive bacteria. They are remarkably promiscuous and can conjugate between bacteria belonging to different species and genera. Transposon-promoted conjugation may be similar to F plasmid-promoted conjugation, as it appears that only one strand of the ...

Immunopotentiating conjugates

Vaccine, 1985
Current interest in the development of sub-cellular vaccines and in cancer immunotherapy has rekindled interest in immunopotentiating agents. In addition, peptide sequences of protective antigens are being synthesized or genetically engineered and it is likely that these peptides will have a small relative molecular mass and be non-immunogenic by ...

Conjugate regenerative dividers

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2004
We discuss a novel design of a self-starting regenerative divider that permits division by 3, 4, 5, 6 ... instead of the usual 2. This is accomplished by having the loop oscillate simultaneously at two harmonically related conjugate frequencies, e.g., at nu/4 and 3nu/4.

Molecular Conjugates

2005
Molecular conjugates are nanometer-sized entities consisting of synthetic materials (lipids, polycations, targeting agents, and so on) and nucleic acids. These composites are delivery vehicles that function to provide the transport of nucleic acids to sites of action. Recently, great progress has been made in the construction of these nonviral delivery
