This new article publication from Acta Pharmaceutica Sinica B, discusses the construction of a localized immune niche via supramolecular hydrogel vaccine to elicit durable and enhanced immunity against infectious diseases.
Vaccines represent one of the most potent strategies for protecting humans from the threat of infectious diseases. Conventional vaccines elicit acquired immunity by mimicking pathogen characteristics; however, their protective efficacy is limited by inadequate spatiotemporal control of antigen delivery, resulting in suboptimal antigen exposure in lymphoid tissues and transient adaptive immune activation. The authors of this article developed a self-assembling peptide-based supramolecular hydrogel vaccine to establish a localized immune niche, demonstrating its remarkable efficacy in inducing durable and potent immunity against infectious diseases. It was found that this in situ-formed supramolecular hydrogel vaccine serves as a reservoir for antigens and adjuvants while recruiting antigen-presenting dendritic cells (DCs) to accumulate within the scaffold. With the aid of adjuvant, the DCs exhibit enhanced antigen processing and presentation, creating an immunologically active niche that triggers robust B cell and T cell responses. Following a single vaccination, mice immunized with the hydrogel vaccine developed robust humoral immunity and sustained antibody production for 112 days, achieving potent neutralization activity. This study offers a novel approach to spatiotemporal control of vaccine responses that enables durable and enhanced immunity against infectious diseases.

This new article publication from Acta Pharmaceutica Sinica B, discusses the deep learning-based discovery of tetrahydrocarbazoles as broad-spectrum antitumor agents and click-activated strategy for targeted cancer therapy.
Phenotypic screening has played an important role in discovering innovative small-molecule drugs and clinical candidates with unique molecular mechanisms of action. However, conducting cell-based high-throughput screening from vast compound libraries is extremely time-consuming and expensive. Fortunately, deep learning has provided a new paradigm for identifying ...

This new article publication from Acta Pharmaceutica Sinica B, discusses DHL-11, a novel prieurianin-type limonoid isolated from Munronia henryi, targeting IMPDH2 to inhibit triple-negative breast cancer.
Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, characterized by the poorest prognosis, and poses a significant threat to women's health. In this study two novel prieurianin-type limonoids extracted from Munronia henryi were identified, one of which, named DHL-11, exhibited antitumor activity ...

This new article publication from Acta Pharmaceutica Sinica B, discusses how neg-entropy is the true drug target for chronic diseases.
Molecular mechanisms of chronic diseases are complicated, and this impedes drug target identification and subsequent drug discovery. Entropy increase in human body can be considered the root cause of chronic diseases. Accordingly, the inherent neg-entropic mechanisms, for instance the homeostatic mechanisms for metabolism, immunity, self-healing, etc., are true drug targets. Only very few ...

This new article publication from Acta Pharmaceutica Sinica B, discusses an Oxygen-boosted dual-section microneedle patch for enhanced drug penetration and improved photodynamic and anti-inflammatory therapy in psoriasis.
Psoriasis is a prevalent chronic inflammatory skin disorder, characterized by epidermal thickening and an inflammatory hypoxic microenvironment, which significantly hinder drug penetration through the thickened skin and limit the efficacy of photodynamic therapy (PDT). The authors of this article ...

Sepsis is a leading global cause of hospital deaths, occurring when the body’s response to infection damages tissue and causes organs to fail. Africa bears the world’s highest burden of sepsis, with an estimated 48 million cases each year leading to about 11 million deaths. People living with HIV face the greatest risk of dying from the condition.
A new study has found that tuberculosis, a chronic bacterial lung disease, is a major and long-overlooked cause of deadly sepsis among people living with HIV. An associated Phase 3 clinical trial called the ATLAS study found that starting tuberculosis (TB) treatment ...

This new article publication from Acta Pharmaceutica Sinica B, discusses how structure-guided design of picomolar-level macrocyclic TRPC5 channel inhibitors with antidepressant activity.
Recent advances in ion channel structural biology have enhanced structure-based drug design, yet lipid-occupied binding pockets—often large and flat—remain a major hurdle for developing selective small molecules. TRPC5, a brain-enriched channel regulating depression and anxiety, is a promising therapeutic target, but current preclinical candidates suffer from moderate off-target effects. To address ...
