Hydroquinine (Standard) is the analytical standard of Hydroquinine. Hydroquinine (Dihydroquinine) is an anti-bacterial agent that inhibits both Gram-positive and Gram-negative bacteria. Hydroquinine inhibits the growth of multidrug-resistant pseudomonas aeruginosa via the suppression of the arginine deiminase pathway genes. Hydroquinine inhibits Plasmodium falciparum and Plasmodium berghei. Hydroquinine displays anti-malarial and demelanizing activities. Hydroquinine effectively induces specific RND-type efflux pump systems in Pseudomonas aeruginosa, particularly the MexCD-OprJ and MexXY efflux pumps. Hydroquinine inhibits Pseudomonas aeruginosa adhesion and biofilm formation. Hydroquinine serves as a precursor for derivatives such as C9 epihydroquinine, 9-acetoxy-10,11-dihydroquinine, and 10,11-dihydroquinine monohydrochloride.

LB 11058 is a Cephalosporin Antibacterial agent. LB 11058 inhibits the growth of pathogenic bacteria, including multidrug-resistant staphylococci and streptococci, but shows weak activity against Enterococcus faecium, Corynebacterium species, Enterobacteriaceae and non-fermenting Gram-negative bacilli. LB 11058 can be used in bacterial infection research.

Doxycycline fosfatex is an orally active highly lipophilic, tissue-permeable MMP inhibitor with broad-spectrum antibacterial activity. Doxycycline fosfatex is also a semi-synthetic antibiotic with chelating properties, which blocks bacterial protein synthesis and inhibits extracellular matrix degradation through interactions with zinc and fosfatex atoms. Doxycycline fosfatex also inhibits mitochondrial biogenesis, translation, and the expression of respiratory chain proteins. Doxycycline fosfatex induces apoptosis, inhibits autophagy and EMT, downregulates stem cell markers, and activates the PI3K-AKT pathway, thereby effectively inhibiting the viability and proliferation of cancer cells such as breast cancer cells. Doxycycline fosfatex also promotes the survival and self-renewal of embryonic stem cells and neural stem cells, and reduces the frequency of medium changes in culture. Doxycycline fosfatex has been applied in studies related to breast cancer, prostate cancer, bladder cancer, and other cancers.

Chicamycin B has anti-tumor activity and weak anti-Gram-positive bacteria activity.
