Full Text DESCRIPTION
NOVEL ARYLAMIDINE DERIVATIVE OR SALT THEREOF
TECHNICAL FIELD
The present invention relates to a novel
arylamidine derivative having an antifungal activity,
or a salt thereof. In addition, it relates to an
antifungal agent containing the arylamidine derivative
as active ingredients.
BACKGROUND ART
Serious deep mycosis such as invasive
candidiasis often becomes a fatal disease. Originally,
it has been considered that a principal protective
mechanism on the side of a host organism to Mycomycetes
such as Candida would be nonspecific immunization by
neutrophils. When this protective mechanism normally
functions, there is a little risk of becoming infected
with Mycomycetes. However, in recent years, a risk of
developing deep mycosis has been increased because of
increase in the number of patients with underlying
diseases decreasing the immunological function of an
organism, such as malignant tumors (in particular,
hemopoietic malignant tumors such as acute leukemia or
malignant lymphoma) or AIDS, heavy use of anticancer
agents or immunosuppressive agents, heavy use of
antibacterial antibiotics or steroid hormone, long-term

use of central venous hyperalimentation or venous
catheterization, and so on (Rinsho to Biseibutsu
(Clinics and Microorganisms), vol. 17, p. 265, 1990).
The number of agents applied to a treatment
for such deep mycosis is much smaller than that of
antibacterial agents. There are only 6 types of
agents, such as amphotericin B, flucytosine,
miconazole, fluconazole, itraconazole, and micafungin.
Amphotericin B has an extremely strong
fungicidal action to Mycomycetes. However, at the same
time, it has a problem regarding strong side effects
such as nephrotoxicity, and therefore, to use the agent
in a clinical situation is limited. In addition,
flucytosine has a problem that the agent causes rapid
development of resistance when it is chronically used.
Accordingly, at present, this agent is seldom used
singly. Micafungin has a low activity to the
Cryptococcus species. Other agents are generically
called azole antifungal agents in terms of their
structural characteristics. There is a general
tendency that the fungicidal action of these agents to
Mycomycetes is poorer than that of amphotericin B.
However, considering both effectiveness and safety,
azole antifungal agents are most frequently used at
present ((Rinsho to Biseibutsu (Clinics and
Microorganisms), vol. 21, p. 277, 1994).
Currently, fluconazole-resistant Candida
albicans (C. albicans) has been detected with a high

frequency of 30% or more in oropharyngeal candidiasis
lesion of AIDS patients to whom fluconazole had been
repeatedly administered. Moreover, most of the
resistant strains show cross resistance to itraconazole
and other azole agents. Furthermore, separation of the
resistant strains has also been reported regarding non-
AIDS patients who developed chronic mucocutaneous
candidiasis or deep candidiasis {Rinsho to Biseibutsu
(Clinics and Microorganisms), vol. 28, p. 57, 2001).
Thus, if a limited number of agents have a
problem regarding resistance, it will inevitably affect
the management of patients with deep mycosis, the
number of which is being increased (Rinsho to
Biseibutsu (Clinics and Microorganisms), vol. 28, p.
51, 2001).
Accordingly, it is strongly desired that an
antifungal agent will be developed, whose action
mechanism differs from those of the existing agents and
which has effects on Mycomycetes resistant to azole
agents, while having a little side effects.

Test example 1 Antifungal action
50% growth inhibitory concentration (IC50) was
measured according to the microbroth dilution method,
using, as a reference, the antifungal agent sensitivity
test method proposed by the subcommittee for the
antifungal agent sensitivity test, the Japanese Society
for Medical Mycology (Japanese Journal of Medical

Mycology, vol. 36, No. 1, pp. 62 to 64, 1995).
Synthetic amino acid medium, fungal (SAAMF,
manufactured by Nippon Bio-Supp. Center) was used as a
medium for measurement of sensitivity. Candida
albicans TIMM 1623 was cultured at 30°C overnight on a
Sabouraud agar plate medium (Eiken Chemical Co., Ltd.),
and the obtained culture was suspended in a sterilized
physiological saline solution. Thereafter, the
suspension was diluted with a measurement medium such
that the number of cells became 1 x 104 cells/ml,
thereby producing an inoculum organism solution. 175
µl of a medium, 5 µl of a test agent (an agent diluted
solvent in a growth control well), and 20 µl of the
inoculum organism solution were added to a 96-well
microplate (flat bottom, manufactured by Sumitomo
Bakelite Co., Ltd.), and the mixture was stirred with a
mixer. Thereafter, using a well Reader SME3400
(Scinics Co., Ltd.), an initial turbidity at a
wavelength of 630 nm was measured. The above mixture
was cultured at 35°C, and 36 hours later, a final
turbidity was measure in the same manner. For an
agent-diluted line, values were obtained by subtracting
the initial turbidities from the final turbidities.
For a growth control line also, values were obtained by
subtracting the initial turbidities from the final
turbidities. IC50 was defined as the lowest agent
concentration among the test agent concentrations
having a turbidity equal to or lower than the 50% value

(IC50 calculated value) of a value obtained by
subtracting the initial turbidity of a growth control
from the final turbidity thereof. The results
regarding the IC50 value to each cell strain are shown
in Table 14.

Test example 2 Therapeutic effect of Candida albicans
on mouse systemic infection
Candida albicans TIMM 1623 was cultured at
30°C overnight on a Sabouraud agar plate medium (Eiken
Chemical Co., Ltd.), and the obtained culture was
suspended in a sterilized physiological saline
solution. Thus, a fungal solution for infection,
having a concentration of 1 x 107 cells/ml, was
prepared. This fungal solution was inoculated in a
concentration of 0.2 ml (2 x 106 CFU/mouse) into the
tail vein of each of five ICR male mice (4-week-old,
body weight of 20 ± 1 g). 2 hours later, 0.2 ml of a

solution, which had been prepared by dissolving a test
compound into a sterilized physiological saline
solution and setting the concentration at 0.01 mg/ml,
was administered once into the dorsal subcutis of each
mouse. To mice of a control group, an equal amount of
a sterilized physiological saline solution was
administered.
Viability of the mice was observed until the
14th day after the infection, and the cumulative
survival rate (T/C) of the treatment group to the
control group was calculated, and the obtained value
was used as an index of the life-prolonging effect.
As a result, it was found that, in the case
of the compound in Example 24, T/C was 180 with
administration of 0.1 mg/kg.
Test example 3 Therapeutic effect of Candida albicans
on mouse systemic infection
Candida albicans TIMM 1623 was cultured at
30°C overnight on a Sabouraud agar plate medium (Eiken
Chemical Co., Ltd.), and the cultured fumgus was
suspended in a sterilized physiological saline
solution. Thus, a fungal solution for infection,
having a concentration of approximately 107 cells/ml,
was prepared. 0.2 ml of this fungal solution was
inoculated into the tail vein of each of five ICR male
mice (4-week-old, body weight of 20 ± 1 g). 2 hours
after the infection, 0.2 ml of a solution, which had

been prepared by dissolving a test compound into a
sterilized physiological saline solution and adjusting
the concentration at 0.01 mg/ml, was administered once
into the dorsal subcutis of each mouse. From the
following day, the same solution was administered
thereto once a day for 6 days. Thus, the above
solution was administered into the dorsal subcutis of
the mice 7 times in total. To mice of a control group,
an equal amount of a sterilized physiological saline
solution was administered. Viability of the mice was
observed until the 28th day after the infection.
As a result, it was found that the mice of
the control group all died by the 28th day after the
infection, but that the mice of the compound
administration groups in Example 24, Example 40-2, and
Example 56 survived at a ratio of 3/5, 4/5, and 4/5,
respectively.
