GB-1a
GB-1a (Biflavanone GB-1a) is a biflavanone HIV-1 reverse transcriptase inhibitor (IC50=236 μM), with an EC50 of 38.0 μM for HIV-1 replication. GB-1a can block the conversion of HIV-1 genomic RNA to DNA and can be used in research related to AIDS (HIV-1 infection). GB-1a can be naturally extracted from the heartwood of Garcinia multiflora Champ.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
