AIDS caused by HIV-1, is a major threat to human being. An anti-HIV formulation from Chinese herbs, so called "Qu Du Zeng Ning", have been recently developed. In this work, the pharmacodynamics of the formulation in vitro was studied. The results showed that Qu Du Zeng Ning inhibit the replication of HIV-1 efficiently in all cell-based assay, with IC50 at 105.2, 70.7, 77.4 microg mL(-1), separately. A significant synergy between the formulation and zidovudine (AZT) was observed, and it also showed a potent activity against HIV-1 drug-resistant mutant.

The lymphatic vasculature plays critical roles in maintaining fluid homeostasis, transporting lipid, and facilitating immune surveillance. A growing body of work has identified lymphatic dysfunction as contributing to the severity of myriad diseases and to systemic inflammation, as well as modulating drug responses. Here, we review efforts to reconstruct lymphatic vessels in vitro toward establishing humanized, functional models to advance understanding of lymphatic biology and pathophysiology.

This work describes the synthesis, characterization, and antibacterial properties of four bile acid-triclosan conjugates. The in vitro antibacterial activity of synthetic bile acid-triclosan conjugates was investigated against a panel of Gram-positive and Gram-negative bacteria. Conjugates and show high activity against (ATCC25922), with IC values of 2.

N-heterocyclic carbene (NHC)-protected gold nanoclusters display high stability and high photoluminescence, making them well-suited for fluorescence imaging and photodynamic therapeutic applications. We report herein the synthesis of two bisNHC-protected Au nanoclusters with π-extended aromatic systems. Depending on the position of the π-extended aromatic system, changes to the structure of the ligand shell in the cluster are observed, with the ability to correlate increases in rigidity with increases in fluorescence quantum yield.

Acrolein (ACR) present in vivo and in vitro can damage proteins and DNA, linking it to various chronic diseases. In this paper, ergothioneine (EGT), abundant in edible mushrooms, has been studied for its ability to trap ACR and its reaction pathway with ACR at high temperatures using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS/MS). We synthesized the adducts (EGT-ACR-1 and EGT-ACR-2), elucidating their structure and reaction site through HRMS and nuclear magnetic resonance.

Designing binders to target undruggable proteins presents a formidable challenge in drug discovery. In this work, we provide an algorithmic framework to design short, target-binding linear peptides, requiring only the amino acid sequence of the target protein. To do this, we propose a process to generate naturalistic peptide candidates through Gaussian perturbation of the peptidic latent space of the ESM-2 protein language model and subsequently screen these novel sequences for target-selective interaction activity via a contrastive language-image pretraining (CLIP)-based contrastive learning architecture.
