20S proteasome.
Topoisomerase I and II.

Aclacinomycin A could efficiently enter living cells and emit fluorescence in situ . Aclacinomycin A (10 μM for 15 min) is sufficient for clear detection of fluorescence in most of the cultured cells. Aclacinomycin A treatment (10 μM Acla for 15 min) results in approximately 20% dead (or nearly dead) cells.
Aclacinomycin A (Aclarubicin) effectively induces incorporation of exon 7 into SMN2 transcripts from the endogenous gene in type I SMA fibroblasts as well as into transcripts from a SMN2 minigene in the motor neuron cell line NSC34 .

Aclacinomycin A is very well absorbed in mice, rats, and dogs after its oral administration. The oral LD ₅₀ (76.5 mg/kg) is about twice the iv LD ₅₀ (35.6 mg/kg) in mice ^[4 .
Aclacinomycin A (0.75-6 mg/kg, ip daily) dose-dependently exhibits tumor growth in mice-based Leukemia P-388 model ^[4 .
