Harnessing a catalytic lysine residue for the one-step preparation of homogeneous antibody-drug conjugates

open access: yesNature Communications, 2017
Current strategies for producing antibody-drug conjugates often rely on inefficient conjugation chemistry or on generating mutations in the antibody sequence.

Effect of charged lipids on the ionization behavior of glutamic acid containing transmembrane helices [PDF]

open access: yes, 2020
Transmembrane proteins make up critical components of living cells. Protein function can be greatly impacted by the charged state of its respective components, the side chains of amino acid residues.

De resíduo a insumo: a construção do caminho para uma química mais limpa através de um projeto de ensino From residue to input: building a road to clean chemistry through an educational project

open access: yesQuímica Nova, 2008
The discussion among teachers, students, and technicians about the destination of residues from chemistry laboratories led to a research project whose results were incorporated into a course in its daily practices.

Influence of the isomeric composition of the acceptor on the performance of organic bulk heterojunction P3HT:bis-PCBM solar cells [PDF]

open access: yes, 2012
We synthesized three isomeric subpopulations of bisadduct analogues of [6,6]-phenyl-C61-butyric acid methyl ester (bis-PCBM) via tether-directed control.

Functional differences of iodinated obestatin peptides: in vitro metabolic stability profile [PDF]

open access: yes, 2010
Peptides are small polymers of 50 amino acids, situated between organic molecules and proteins. Most peptides perform a biochemical-physical function and are therefore considered as potential drugs.

Allo-network drugs: Extension of the allosteric drug concept to protein-protein interaction and signaling networks [PDF]

open access: yes, 2013
Allosteric drugs are usually more specific and have fewer side effects than orthosteric drugs targeting the same protein. Here, we overview the current knowledge on allosteric signal transmission from the network point of view, and show that most ...

Per- and Polyfluoroalkyl Substance Levels in Commercial and Home-Produced Eggs in Croatia

open access: yesFoods
The aim of this study was to measure per- and polyfluoroalkyl substance (PFAS) levels in eggs collected in Croatia and to identify differences between commercially produced eggs (cage, barn, and organic) and home-produced eggs (HPE).

Synthesis and Anticancer Activity of Glucosylated Podophyllotoxin Derivatives Linked via 4β-Triazole Rings

open access: yesMolecules, 2013
A series of 4β-triazole-linked glucose podophyllotoxin conjugates have been designed and synthesized by employing a click chemistry approach. All the compounds were evaluated for their anticancer activity against a panel of five human cancer cell lines ...

Peripherally-metallated porphyrins: meso-n1-porphyrinyl-platinum(II) complexes of 5,15-diaryl- and 5,10,15-triarylporphyrins [PDF]

open access: yes, 2002
Attempted metathesis reactions of peripherally-metallated meso-η1-porphyrinylplatinum(II) complexes such as trans-[PtBr(NiDPP)(PPh3)2] (H2DPP = 5,15-diphenylporphyrin) with organolithium reagents fail due to competitive addition at the porphyrin ring ...

Novel polymer coupling chemistry based upon latent cysteine-like residues and thiazolidine chemistry

open access: yesPolymer Chemistry, 2010
Chain end functional polymers were prepared via reversible addition–fragmentation transfer (RAFT) polymerization techniques that were further chain extended with acrylonitrile. Under reducing conditions, latent cysteine-like residues were exposed at the chain ends.
