New Quinoline-Based Heterocycles as Anticancer Agents Targeting Bcl-2

Molecules, 2019
The Bcl-2 protein has been studied as an anticancer drug target in recent years, due to its gatekeeper role in resisting programmed cancer cell death (apoptosis), and the design of BH3 domain mimetics has led to the clinical approval of Venetoclax (ABT ...

Synthesis of 1,2,3-triazoles and applications in the synthesis of BODIPY triazoles

, 2020
The 1,2,3-triazole ring is an important heterocycle which has found wide applications due to its interesting properties. Mainly due to the advent of the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, 1,2,3-triazoles are nowadays unavoidable in the chemical literature. In the past decade, the development of transition metal-free synthetic

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Unlocking Catalyst Activation as a Critical Bottleneck in Cross‐Coupling Reactions: Room‐Temperature Couplings of Weak Nucleophiles Enabled by [Pd(1‐MeNAP)TFA]2 Precatalysts

Angewandte Chemie International Edition, EarlyView.
In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Discovery of CRBN‐based molecular glue degraders targeting WIZ transcription factor

Bulletin of the Korean Chemical Society, EarlyView.
This work reports the discovery of 9l, a novel cereblon‐based molecular glue degrader which targets the WIZ transcription factor. Compound 9l facilitates WIZ‐CRBN ternary complex formation to degrade WIZ, subsequently inducing γ‐globin expression in HUDEP‐2 cells and highlighting its potential as a sickle cell disease therapy.
