It is produced by the strain of Trichoderma harzianum. It has weak anti-gram-positive bacterial activity and anti-tumor effect, it can inhibit lymphoblastic leukemia L1210 and leukemia P388 with IC50 of 0.26 μg/mL. It inhibits the binding of viral particle regulatory (REV) proteins to [33P] labeled viral particle regulatory effector element (RRE) RNA, IC50 is 2.0 μmol/L. 200 μg/mL of Harziphilone does not protect CEM-SS cells from HIV-1 infection, and 38μmol/L of Harziphilone has cytotoxicity to mouse tumor cells M-109.
