First nitrogen mustard
Can be given as only ….
What happens if given topical
Mechlorethamine
Iv-local severe vesicant
If topical-cutaneous T cell lymphoma
Prodrug in nitrogen mustard
S/e of cyclophosphamide is due to ….
Cyclophosphamide —> phosphor amide mustard+ acrolein.
Haemorrhagic cystitis is due to Acrolein; protected by mesna.
Very high doses of cyclophosphamide causes ……(3)

Chloracetaldehyde causes Nephro toxicity
Acrolein—> hge cystitis
More harmful than cyclophosphamide.
Increased neurotoxicity,nephrotoxicity,hge cystitis, platelet suppression.

Radiomimetics - action ~ ionising radiation
PCT,DCT
Nephro toxicity
Ototoxicity- high frequency hearing loss
Neurotoxicity- sensory neuropathy
S/e of carboplatin-
S/e of oxaliplatin (2)
similar to cisplatin but milder, more myelosuppression.
