Antimicrobial Library

v1.0 (alpha)

This library contains extensive information on antimicrobial drugs and is aimed at researching selection of drugs or drug combination, based on target protein or known interactions with human metabolism.
The search bar allows you to refine entries to eg. "azole" or search for a specific name / term. You can also sort by column.
The export buttons can be used to download and work with this data offline or in other tools.

[Unfortunately, this rich dataset is not designed for browsing on mobile devices and is best viewed on a laptop / desktop computer.

Cleavage of endoperoxide bridge produces free radicals in presence of iron, damaging parasite proteins and membranes (rapidly cidal). Active against blood stages of Plasmodium, including falciparum.	Short half-life (~1 hour). Induces CYP2B6 and 3A4 via PXR/CAR activation - can reduce levels of itself and co-administered drugs over time. Generally well-tolerated; transient neutropenia possible.

Proguanil: prodrug converted to cycloguanil, a dihydrofolate reductase inhibitor (enhances atovaquone effect). Used together (Malarone) for malaria.	Atovaquone: >99% protein-bound, excreted largely unchanged in feces. Inhibits no major CYPs (but rifampin reduces atovaquone levels ~50% by inducing clearance). Proguanil: metabolized by CYP2C19 to active cycloguanil (poor CYP2C19 metabolizers have reduced efficacy). Generally well tolerated; atovaquone can cause transient LFT elevations; proguanil can cause mouth ulcers/hair loss (rare).	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	1	0	0	0	0	0	0	1	0	0	0

Not absorbed orally (given IV for systemic infections). Renal excretion - requires dose adjustment in renal dysfunction. No CYP metabolism.

Fungistatic/cidal (species-dependent).	Metabolized by CYP2C19, 2C9, 3A4; inhibits CYP3A4, 2C9, 2C19 - significant interactions (cyclosporine, tacrolimus require dose reduction). Nonlinear pharmacokinetics. Off-target: visual disturbances (reversible), hallucinations, QT prolongation.	0	0	1	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0
