Inflammatory processes occur as a generic response of the immune system and can be triggered by various factors, such as infection with pathogenic microorganisms or damaged tissue. Due to the complexity of the inflammation process and its role in common diseases like asthma, cancer, skin disorders or Alzheimer's disease, anti-inflammatory drugs are of high pharmaceutical interest. Nature is a rich source for compounds with anti-inflammatory properties. Several studies have focused on the structural optimization of natural products to improve their pharmacological properties. As derivatization through total synthesis is often laborious with low yields and limited stereoselectivity, the use of biosynthetic, enzyme-driven reactions is an attractive alternative for synthesizing and modifying complex bioactive molecules. In this minireview, we present an outline of the biotechnological methods used to derivatize anti-inflammatory natural products, including precursor-directed biosynthesis, mutasynthesis, combinatorial biosynthesis, as well as whole-cell and in vitro biotransformation.

The Centers for Disease Control and Prevention's Partnering for Vaccine Equity program was developed during the COVID-19 public health emergency to fund more than 500 community-based organizations working to improve vaccine equity. Organizations were supported by a virtual learning community where members received tailored learning content, peer-to-peer learning opportunities, and resources that facilitated deployment of vaccine-related programming during a dynamic pandemic. Process evaluation metrics indicate successful implementation of the learning community.

Background: COVID-19 still poses a major public health challenge worldwide and vaccination remains one of the major interventions to control the disease. Different types of vaccines approved by the World Health Organization (WHO) are currently in use across the world to protect against the disease. This study assessed the prevalence and pattern of adverse events following immunization (AEFI) after receiving COVID-19 vaccine (the Oxford-AstraZeneca vaccine) among the adult population in Sokoto metropolis, North-west, Nigeria.

2-Quinolones represent a versatile class of compounds that are prevalent in natural and medicinally relevant molecules. Here we report a new approach to the selective formation of these structures. By gold catalysis, a range of benzaldehyde-tethered ynamides reacted with anilines, leading to 4-amino-3,4-dihydro-2-quinolones with high efficiency and excellent diastereoselectivity in dichloromethane.

Astracondensatol D (), a pentacyclic triterpenoid featuring an uncommon 6/6/5/6-fused ring system, along with its precursor astracondensatol E (), and two simplified 20(27)-octanorcycloastragenol derivatives ( and ) were isolated from for the first time. Classical NMR spectroscopic data, integrated with NMR and DP4+ calculations, unambiguously determined their absolute stereostructures. X-ray crystallography provided independent confirmation of the structure of compound .

Current influenza vaccines are not effective in conferring protection against antigenic variants and pandemics. To improve cross-protection of influenza vaccination, we developed a 5xM2e messenger RNA (mRNA) vaccine encoding the tandem repeat conserved ectodomain (M2e) of ion channel protein M2 derived from human, swine, and avian influenza A viruses. The lipid nanoparticle (LNP)-encapsulated 5xM2e mRNA vaccine was immunogenic, eliciting high levels of M2e-specific IgG antibodies, IFN-γ+ T cells, T follicular helper cells, germinal center phenotypic B cells, and plasma cells.
