| Description: |
Tectol has anti-plasmodial activity, it as a moderately active growth inhibitor with an IC50 3.44±0.20μM. It exhibited significant activity against human leukemia cell lines HL60 and CEM. Tectol may cause itchy dermatitis, the dermatitis appeared on the neck, upper legs, underarms, and trunk area. |

| J Nat Prod. 2001 Jun;64(6):792-5. | | Chemical constituents from Lippia sidoides and cytotoxic activity.[Pubmed: 11421746 ] |
METHODS AND RESULTS:
Eleven known compounds and a new prenylated naphthoquinone, lippsidoquinone (13), were isolated from ethanol extracts of Lippia sidoides. Their structures were established by a combination of 1D and 2D NMR, IR, and EIMS spectral data analysis. The cytotoxic properties of compounds 3--13 were evaluated against HL60, SW1573, and CEM cell lines.
CONCLUSIONS:
Only tectol (6) and lippsidoquinone (13) exhibited significant activity against human leukemia cell lines HL60 and CEM. |

| Contact Dermatitis. 1987 Aug;17(2):115-6. | | Allergy to spermicidal lubricant in a contraceptive.[Pubmed: 3652700 ] |
METHODS AND RESULTS:
Allergic contact dermatitis is reported in a patient using a condom with the spermicidal lubricant Tectol. A 36 year old female, with no history of dermatitis or pruritus of the vagina or vulva, experienced itchy dermatitis 24-48 hours after her partner used a Durex Top Safe contraceptive containing Tectol. The dermatitis appeared on the neck, upper legs, underarms, and trunk area. When another contraceptive was used Durex Featherlite (without Tectol), the patient experienced no problems.
CONCLUSIONS:
Patch tests concluded that the Tectol lubricant was the cause for the reaction in the patient. Transmission of the lubricant to the patient occurred when the patient's partner, after handling the contraceptive (Durex Top Safe) during intercourse, placed his hands on the patient's body. To which exact element of Tectol the patient was sensitized could not be determined as the patient refused further treatment. |
