AAV library screening identifies novel vector for efficient transduction of human aorta.

Targeted gene delivery to vascular smooth muscle cells (VSMCs) could prevent or improve a variety of diseases affecting the vasculature and particularly the aorta. Thus, we aimed to develop a delivery vector that efficiently targets VSMCs. We selected engineered adeno-associated virus (AAV) capsids from a random AAV capsid library and tested the top enriched motifs in parallel screening through individual barcoding.

Extension of the π-system of monoaryl-substituted norbornadienes with acetylene bridges: influence on the photochemical conversion and storage of light energy.

The photochromic norbornadiene/quadricyclane pair is a promising system for molecular solar thermal (MOST) energy storage, with which solar energy may be converted, stored, and released as heat in one integral molecular system. Herein, we present the synthesis of mono-, bis-, and tris-norbornadiene derivatives with alkynylbenzene and alkynylnaphthalene core units, along with studies of their photochemical properties. The target compounds were synthesized by Sonogashira-Hagihara coupling reactions of 2-bromonorbornadiene and the corresponding arylacetylenes.

Targeting PARP-1 and DNA Damage Response Defects in Colorectal Cancer Chemotherapy with Established and Novel PARP Inhibitors.

The DNA repair protein PARP-1 emerged as a valuable target in the treatment of tumor entities with deficiencies of , such as breast cancer. More recently, the application of PARP inhibitors (PARPi) such as olaparib has been expanded to other cancer entities including colorectal cancer (CRC). We previously demonstrated that PARP-1 is overexpressed in human CRC and promotes CRC progression in a mouse model.

Addressing the Intracellular Vestibule of the Plasmodial Lactate Transporter PfFNT by p-Substituted Inhibitors Amplifies In Vitro Activity.

Inhibition of the lactate transporter PfFNT is a valid novel mode of action against malaria parasites. Current pyridine-substituted pentafluoro-3-hydroxy-pent-2-en-1-ones act as substrate analogs with submicromolar EC in vitro, and >99.7% activity in mice.

A Novel 3/4-Fused Indole Scaffold through Acid-Catalyzed Cascade Reaction.

3,4-bridged indoles are underrepresented among the vast number of indoles described in the literature. Attempts to access 3,4-macrocyclized indoles led to the unexpected formation of a novel tetracyclic indole through intramolecular acid-catalyzed ring contraction. The herein-established one-step synthetic route provides an excellent medicinal chemistry platform for the construction of screening libraries covering a unique chemical space of indoles.
