Bulk: As a bulk chemical, didemnin B is found to be stable at 25 ± 2 °C for 3 weeks. At the end of 4 weeks, approximately 2% decomposition has occurred. When stored at 45 °C, didemnin B appeared stable for 2 weeks; after this time, it slowly decomposed to an approximate 7% loss at the end of 4 weeks (HPLC). Solution: As a 6 mg/mL 50% aqueous ethanol solution at room temperature (25 ± 2 °C) didemnin B appeared stable for at least 26 hours (HPLC).

Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection.

Substances that inhibit or prevent the proliferation of NEOPLASMS.

Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.

Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
