Solvent‐Free Process for Preparing Metal‐Organic Framework Composites Based on Carbon‐Based Quantum Dots and Their Derivatives as Drug Delivery Systems for Andrographolide

open access: yesChemistry – A European Journal, EarlyView.
Andrographolide (ADG) was conjugated with MOFs (MIL‐53(Al), ZIF‐8) carbon‐based quantum dots (CBQDs) and doped carbon‐based quantum dots (D‐CBQDs) using the green approach of high‐pressure (0.3 GPa) solid phase contact. This method enhances the drug solubility, as indicated by changes in hydrophobicity observed via 1H NMR. Abstract Andrographolide (ADG)

In vitro screening and in vivo evaluation of antiparasitic phytochemicals against Cryptocaryon irritans in pompano, Trachinotus ovatus

open access: yesJournal of the World Aquaculture Society, Volume 53, Issue 6, Page 1084-1100, December 2022., 2022
Abstract Cryptocaryon irritans, one of the most devastating holotrichous ciliated protozoans, causes massive economic losses in the pompano, Trachinotus ovatus, mariculture industries. Considering the many advantages of phytochemicals, such as low cost, low residuals, and low pollution, they can be a good alternative for the prevention and control of C.

Computational Analysis of the Stereoselective Synthesis of Substituted Pyrrolidines [PDF]

open access: yes, 2015
In this work we use computational methods to study the aza-Cope-Mannich tandem reaction of a substituted oxazolidine to form a formyl pyrrolidine. Pyrrolidine structural motifs are found in natural products, pharmaceutical compounds, and chiral catalysts.

Integrating Catalysis and Analysis: Accelerated Asymmetric Reaction Development with a Multitasking Reactivity Umpolung/Chiroptical Reporter Auxiliary

open access: yesChemistry – A European Journal, Accepted Article.
High‐throughput asymmetric reaction development of an organocatalytic Michael addition is achieved by using a readily available isatin molecule as amine protecting group, reagent for reactivity Umpolung, and as chiroptical yield and enantioselectivity reporter.

Lewis‐X‐Containing Triterpenoid Saponins Inhibit DC‐SIGN‐ and L‐SIGN‐Mediated Transfer of HIV‐1 Infection

open access: yesChemistry – A European Journal, EarlyView.
The convergent synthesis of Lewis‐X‐containing betulinic acid and echinocystic acid saponins (1 and 2) is presented. The synthetic saponins were shown to inhibit, at the low micromolar range, the DC‐SIGN‐ and L‐SIGN‐mediated transfer of HIV‐1 infection to CD4‐positive cells, whereas free Lewis‐X, aglycones, and structurally similar triterpenoid ...
