Definition
ChEBI: Tolciclate is a monothiocarbamic ester. It has a role as an antifungal drug.
Indications
The indications for tolciclate are defined by its narrow spectrum and limited to the treatment of dermatophytoses. Because of inadequate penetration into the nail keratin, it is unlikely to be effective for the treatment of onychomycoses. On average, the efficacy of tolciclate in topical therapy of dermatomycoses is lower than that of most other antimycotics for topical treatment.
Manufacturing Process
Thiophosgene (1.15 g, 0.01 mol) in chloroform (40 ml) was slowly treated at
room temperature with sodium 1,4-methano-1,2,3,4-tetrahydro-6-
naphthoxide (1.82 g, 0.01 mol). After 30 minutes, N-methyl-m-toluidine (2.42
g, 0.02 mol) in chloroform (40 ml) was added dropwise to the solution so
obtained at room temperature. The reaction mixture was stirred for 48 hours
at room temperature and then refluxed for 2 hours. The solvent was
evaporated, and the residue redissolved in water and extracted repeatedly
with diethyl ether. The organic phase was dried (Na2SO4) and evaporated to dryness to give, after crystallization from isopropanol, O-(1,4-methano-
1,2,3,4-tetrahydro-6-naphthyl)-N-methyl-N-(m-tolyl)-thiocarbamate (1.3 g)
melting point 92°C to 94°C.
Therapeutic Function
Topical antimycotic
Antimicrobial activity
In vitro, tolciclate has a narrow activity spectrum with good efficacy only towards dermatophytes. Isolates of susceptible species showing primary resistance or developing secondary resistance are rarely observed.
