Use of fluconazole for inhibiting
the growth of cancers
TECHNICAL FIELD
This i~ lion is a ph_ ~ ;c~l c~ that is useful for the v~dtl~ l of canoers
and tumors, paulicuLuly in human and warm blooded animals cc ~ g 2-(2~4~ 1UUIU~
1,3-bis(lH-1,2,4-triazol-1-yl)propan-2-ol and its de.ivdli.~ It can be used in co ~h;. ~I;o~ with
10 other e ' , agents and pùt~ The same ~ on can be used to treat vi~al
BACKGROUND OF THE INVENTION
Canoers, ~ iing IP~ Pm;q, are the leading cause of death in animals and humans The
exa~ cause of I ' is not known, but Unks between certain activities such as smolcing or
15 ~uau~; to c~n~ills;~' ~~ and the i~ :d~ of oertain types of le~ pmiq and tumors has been shûwn
by a number ûf l-,s~-h_.a
Many types of ~h~ ';c agents have been shown to be effective agaunst canoers,
tumors and '~ ~ but not all types of cancer and tumor oells respond to these agents
U~vrvl '~" many of these agents also destroy normal cells The exact . ~ for the
20 action of these ~ ' - agents are not always known
De_pite a~ul~ in the field of canoer and It ~ Il~ll..~.-ta the leading ' , to
dateare~ io~andrhPm~ ' , andbonem.~row1,~"~ h. ~ lvd~h~
are said to fight cancers that are pal~ uly a~;l~ _ Such cytocidal or ~lu~ , agents work
best on canoers with large growth factors, i e., ones whose cells are rapidly dividing To date,
ho.~ , in p~- t;~ estrogen, plUg_it~l - and ~ uat .une, and some ' ~ ed by
a variety of microbes, aLt.~ldtil.g agents, and anti ~;tPC form the bulk of i' , available
to --Y"" Ideally ~Iv~ic agents that have c~rifi~ity for I ' a, canoer and tumor oells
while not affecting normal cells would be e,~ ,..lel~ d ' '- Ullrul: '~" none have been
found and instcad agents which target especially rapidly dividing oells (both diseased and normal)
30 have been used
Clearly, the d~ 1O~ of materials that would target canoer or hP~ Pm;~ oells due to
some unique ~l~c~ for them would be a bl~ll--u..~ll. Alt~,-l~li~.~.ly, .-~ lc that were
~ylolu,~ic to IP~ Pmiq or cancer cells while exerting mild effects on normal cells would be

Any suitable dosage may be given in the method of the h.~ ioll. The type of co-..l u---A
and the carrier a~d the amount will vary widely d~ g on the species of the warm blooded
animal or human, body weight, and the type of caneer or tumor or viral infection being treated.
25 Generally a dosage of between about 1 milligrqm (mg) per kiho~yp~ (Icg) of body weight and about
1000 mg per lcg of body weight is suitable for either the 2-(2,4~ Lv-upl ~ 1)-1,3-bis(lH-1,2,4-
triazol-l-yl)propan-2-ol and its d~.ivd~ s or the ~h- -~h--~ agent. P-~f~ from lS mg
to about 800 mg/lcg of body weight is used. Generally, the dosage in man is lower than for small
warm blooded mqm~qlc sueh as miee. A dosage unit may eomprise a single c-~ v---~A or
30 mixtures thereof with other ,o~ c or other cancer inhihi~ing ~ k The dosage unit
can also cr , ~ diluents, ~ carriers, hl~ and the lilce. The unit may be in solid

Three plates are prepared for each data point. The plates are placed in a 37~C: _l and are
lS removed on day 14 for counting of the number of colonies in each plate. The number of colonioe
(defined as S0 cells) for~ned in the 3 cc---po-~ treated plates is ~,ull~)al~,d to the number of
colonies formed in the 3 control plates, and the percent colonies s~rviving at the . ~r ~ of
