/EXPTL THER/...At all concentrations of /4-chloro-m-cresol/ (4-cmc), the increase in baseline force was significantly greater in the /malignant hyperthermia susceptible/ (MHS) group compared to the /malignant hyperthermia negative/ MHN group (P<0.05). Muscle from 15 MHS patients responded to 4-cmc with increasing force at a threshold concentration of 75 umol/L or less, whereas muscle from 23 MH-non-susceptible (MHN) patients had thresholds of 100 umol/L or more. The accuracy of the chlorocresol test was thus 100% (95% confidence limits 90.75-100%) at a threshold of 75 umol/L. Amplitude of contractures at 2 mmol/L caffeine was not different from contractures at 75 umol/L of 4-cmc in either the MHS or the MHN group (P>0.05). In vivo concentrations of chlorocresol from clinical use of insulin and somatropin are estimated to be 20 times less than the threshold concentration and thus these drugs seem safe in MH patients. 4-chloro-m-cresol may be a suitable aid to clarify puzzling results of standard testing of MH susceptibility.

Four groups of conventional female albino guinea pigs, three per group, were used to determine the bioavailability of PCMC. Occlusive patches of 0.2 mL of a 5% PCMC aqueous suspension stabilized with Carbomer 941, a saturated aqueous solution of 0.38% PCMC, 5% PCMC in olive oil/acetone (4:1), or 5% PCMC in propylene glycol were applied for 24 hr. After 96 hr, the animals were killed and the skin at the site of patch testing was removed for analysis (the patches were kept for analysis to determine the amount of PCMC remaining in the patch material). Fractional sampling of the urine and feces was performed to determine the rate of absorption of PCMC. An additional three animals had been injected with PCMC intraperitoneally to determine the excretion rate. However, no free PCMC was found, indicating rapid metabolism. In determining bioavailability, the calculations were based on the assumption that the saturated PCMC solution is 0.4% (w/v), corresponding to 0.8 mg in 0.2 mL, and that 0.2 mL of the 5% PCMC preparations contained 10 mg of the chemical. The results indicated that 25% of the aqueous PCMC (stabilized with carbomer 941) and 46% of the saturated aqueous PCMC solution remained in the patches. Only 0.2% of the aqueous PCMC (stabilized with carbomer 941) and 0.5% of the saturated aqueous PCMC solution was found in the skin at the patch site. This was compared to 65% of the PCMC in propylene glycol and 66% of the PCMC in olive oil/acetone solutions remaining in the patch; and 0.7% and 1.6%, respectively found in the skin at the patch site. The authors conclude that PCMC was more bioavailable from the aqueous preparations. After 96 hr, 0.2 and 0.5% PCMC was detected at the patch test site in the animals dosed with 5% and saturated aqueous PCMC, respectively, and 0.7 and 1.6% PCMC were found in the skin of the animals patch tested with 5% PCMC in olive oil/acetone and propylene glycol, respectively.

The biocide 4-chloro-3-methylphenol (CMP, CAS number 59-50-7) is a common additive to metal-working fluids (MWF) and building materials. ... In the current study, the in vitro human epidermal permeability of CMP contained in a working dilution of TRIM VX (20% in water) was evaluated and, for comparison, permeability from an aqueous buffer was also assessed. CMP penetration was also measured from transient exposures to 20% TRIM VX. ... Transient (20 or 40 min) exposures of epidermal membranes to 20% TRIM VX (/sample size/ = 4) resulted in total penetration of 4.2 +/- 1.2 and 7.3 +/- 0.8 ug/sq cm, respectively. ...

A pharmacokinetic study was performed in which rats were dosed orally with 300 mg/kg PCMC. PCMC reportedly was eliminated rapidly through the kidneys. Additionally, there is no likelihood of cumulation effects. A corresponding examination of fatty and hepatic tissues from rats that were fed 150-1500 ppm PCMC for up to 13 week reported no indication of an accumulation of PCMC in these tissues.

...In skeletal muscle sarcoplasmic reticulum, 4-chloro-m-cresol was found to be a potent activator of Ca2+ release mediated by a ruthenium red/caffeine-sensitive Ca2+ release channel. In cerebellar microsomes, this compound released Ca2+ from an inositol-1,4,5-trisphosphate-insensitive store, suggesting that there too it was acting at the ryanodine receptor level. When tested on PC12 cells, chlorocresol released Ca2+ from a caffeine- and thapsigargin-sensitive intracellular store. In addition, the compound was capable of releasing Ca2+ after pretreatment of PC12 cells with bradykinin, suggesting that it acts on a channel contained within an intracellular Ca2+ store that is distinct from that sensitive to inositol-1,4,5-trisphosphate. Structure-activity relationship analyses suggest that the chloro and methyl groups in chlorocresols are important for the activation of the ryanodine receptor Ca2+ release channel.

The ryanodine receptor type 1 (RyR1) and type 2 (RyR2), but not type 3 (RyR3), are efficiently activated by 4-chloro-m-cresol (4-CmC). /It was/ previously /shown/ that a 173-amino acid segment of RyR1 (residues 4007-4180) is required for channel activation by 4-CmC ... present study... used site-directed mutagenesis to identify individual amino acid(s) within this region that mediate 4-CmC activation. In RyR1, substitution of 11 amino acids conserved between RyR1 and RyR2, but divergent in RyR3, with their RyR3 counterparts reduced 4-CmC sensitivity to the same degree as substitution of the entire 173-amino acid segment. Further analysis of various RyR1 mutants containing successively smaller numbers of these mutations identified 2 amino acid residues (Gln(4020) and Lys(4021)) that, when mutated to their RyR3 counterparts (Leu(3873) and Gln(3874)), abolished 4-CmC activation of RyR1. Mutation of either of these residues alone did not abolish 4-CmC sensitivity, although Q4020L partially reduced 4-CmC-induced Ca /ion/ transients. In addition, mutation of the corresponding residues in RyR3 to their RyR1 counterparts (L3873Q/Q3874K) imparted 4-CmC sensitivity to RyR3. Recordings of single RyR1 channels indicated that 4-CmC applied to either the luminal or cytoplasmic side activated the channel with equal potency. Secondary structure modeling in the vicinity of the Gln(4020)-Lys(4021) dipeptide suggests that the region contains a surface-exposed region adjacent to a hydrophobic segment, indicating that both hydrophilic and hydrophobic regions of RyR1 are necessary for 4-CmC binding to the channel and/or to translate allosteric 4-CmC binding into channel activation.
