ChEBI

A molecular entity capable of accepting a hydron from a donor (Bronsted acid).

A molecular entity capable of donating a hydron to an acceptor (Bronsted base).

Any drug which causes the onset of an allergic reaction.

A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.

Highly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning. It could be used as an antineoplastic agent, but it might be very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. It could also be used as a component of poison gases.

An agent that suppresses 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. In addition, an immunosuppressive agent is a role played by a compound which is exhibited by a capability to diminish the extent and/or voracity of an immune response.

Any drug which causes the onset of an allergic reaction.

A substance that inhibits or prevents the proliferation of neoplasms.
