Infection

Antibacterial Agent 273 (Compound 15e) is a membrane-targeting antimicrobial agent that disrupts bacterial cell membranes, exhibiting a MIC of 4 μg/mL against Staphylococcus aureus.

N-(3-Hydroxyoctanoyl)-L-homoserine lactone (compound 11), a hydroxyl-containing N-acyl l-homoserine lactone (AHL) ligand, is a competitive AbaR and LasR inhibitor.

Capreomycin IA is a bactericidal agent targeting bacterial ribosomes, with activity limited primarily to mycobacteria. Capreomycin IA blocks translocation of peptidyl-transfer RNA from the A to the P site to inhibit protein synthesis. Capreomycin IA exerts activity against Mycobacterium tuberculosis. Capreomycin IA can be used for the research of tuberculosis.

Tenuigenin (Standard) is the analytical standard of Tenuigenin. This product is intended for research and analytical applications. Tenuigenin is a major active component isolated from the root of the Chinese herb Polygala tenuifolia. Tenuigenin protects against S.aureus-induced pneumonia by inhibiting NF-κB activation. Tenuigenin has anti-inflammatory effect.

Covidcil-19 (compound C5) avidly binds to the revised attenuator hairpin structure of the SARS-CoV-2 frameshifting element (FSE) with a K_d of 11 nM. Covidcil-19 stabilizes the hairpin’s folded state and impairs frameshifting in cells. Covidcil-19 reduces frameshifting efficiency of the SARS-CoV-2 FSE and does not affect SARS-CoV-2 FSE RNA levels. Covidcil-19 inhibits a process essential for SARS-CoV-2 viral propagation.

Hinokitiol (Standard) is the analytical standard of Hinokitiol. This product is intended for research and analytical applications. Hinokitiol is a component of essential oils isolated from Chymacyparis obtusa, reduces Nrf2 expression, and decreases DNMT1 and UHRF1 mRNA and protein expression, with anti-infective, anti-oxidative, and anti-tumor activities.

Endophenazine A has activity against Gram-positive bacteria and filamentous fungi such as mucor and Penicillium. Its weeding ability to Lemna minor is relatively low.

HSV-1-IN-3 (Compound A50) is a HSV inhibitor. HSV-1-IN-3 shows good antiviral efficacy against both Acyclovir (HY-17422) -sensitive and -resistant HSV strains.

3-O-cis-p-Coumaroyl maslinic acid (compound 16) is a natural compound isolated from the ethyl acetate extract of leaves of Miconia albicans.3-O-cis-p-Coumaroyl maslinic acid can inhibit PTP1B, with the IC₅₀ of 0.46 μM, and shows antimicrobial activity on Gram-positive bacteria and yeasts.

Pyrethrolone is a pyrethrolone-type component found in the flowers of Tanacetum cinerariifolium and constitutes a component of natural pyrethrins. Pyrethrolone is generated through the desaturation of jasmolone catalyzed by the cytochrome P450 enzyme TcPYS (CYP82Q3). Pyrethrolone is used in insecticide-related research.

4-Hexen-3-one inhibits the growth of H. pylori strain ATCC 43526 and TDR H. pylori strains. 4-Hexen-3-one inhibits urease activities.

Haliangicin A has anti-filamentous fungi activity, and it also has effect on oomycetes, but has no antibacterial activity.

A25822B is an antifungal agent, with a MIC of 1 μM for Ascosphaera apis. A25822B causes conformational changes in mitochondria and disruption of spore membrane structure. A25822B can be used for the research of bee chalk disease.

Pivmecillinam (FL-1039) is an orally active proagent of mecillinam, an extended-spectrum penicillin antibiotic.

2-Hydroxygentamicin B1 is a 3 aminoglycoside antibiotic with anti-Gram-positive and negative bacteria activity.

Melicopine is an alkaloid found in Z. simulans with antimalarial and anticancer activities. It exhibits inhibitory activity against chloroquine-sensitive 3D7 and chloroquine-resistant Dd2 strains of P. falciparum, with IC₅₀ values of 29.7 and 33.7 µg/mL, respectively. Melicopine is cytotoxic to prostate cancer cells PC-3M and LNCaP (IC₅₀ values of 47.9 and 37.8 µg/mL), but has no effect on non-cancerous HEK293 cells (IC₅₀ greater than 100 µg/mL). Melicopine holds promise for research in anticancer and anti-infection fields.

2-Aminoquinoline (2-Quinolinamine) is a promising compound as bioavailable nNOS inhibitor but suffers from low human nNOS inhibition, low selectivity versus human eNOS, and significant binding to other CNS targets. 2-Aminoquinoline exhibits antiviral activity against the vaccinia virus. 2-Aminoquinoline has the potential for the research of antineurodegenerative agents.

3′-Azido-2′,3′-dideoxy-CTP (AZddCTP) is a cytidine analog containing a 3-azido group. As a chain terminator, 3′-Azido-2′,3′-dideoxy-CTP can be incorporated into the nascent DNA chain by HIV reverse transcriptase. 3′-Azido-2′,3′-dideoxy-CTP terminates DNA synthesis due to the lack of a 3'-hydroxyl group, thereby inhibiting viral replication. 3′-Azido-2′,3′-dideoxy-CTP has IC₅₀ values of 15.6 μM and 160.8 μM for WT HIV and AZT^R HIV. 3′-Azido-2′,3′-dideoxy-CTP has antiviral activity.
