Using a spectrophotometric assay with L-hippuryl-L-histidyl-L-leucine as substrate, s-angiotensin-converting enzyme (SACE) was determined in 85 sarcoidosis patients, 116 healthy controls and 150 patients with various non-sarcoid diseases. The controls showed no sex or age variation and had SACE levels of 24.4 +/- 6.2 U/ml (mean +/- 1 S.D.), giving a normal range (mean +/- 2 S.D.) of 12.0-36.8 U/ml. In contrast, the sarcoidosis patients had SACE values of 38.4 +/- 14.4 U/ml, with the highest values in cases with active sarcoidosis and duration of disease longer than two years (49.0 +/- 12.7 U/ml). A total of 41% of the sarcoidosis patients had elevated SACE, in the chronic active group 85%. Patients with renal failure, Hodgkin's disease and other malignant lymphoma had low SACE, whereas patients with lung cancer and tuberculosis had normal SACE values. Among 266 patients with non-sarcoid diseases and healthy controls, only two had slightly elevated SACE, but so far we have not found SACE above 40 U/ml in other than sarcoidosis patients. An elevated SACE is rather specific in sarcoidosis and seems to be a useful supplement to existing diagnostic measures.

Asaley is an L-leucine derivative of sarcolysin which is more active against some rodent tumors. Studies in the USSR demonstrated activity in patients with ovarian and breast carcinoma, Hodgkin's disease, and multiple myeloma. This study in 73 evaluable patients indicated that an appropriate oral dose for patients with adequate bone marrow is 800 mg/M2/day X 4 days at 5-6 week intervals. The most common toxicities were myelosuppression, nausea, and vomiting. Antitumor activity was observed in 2 of 24 evaluable patients with melanoma, and stabilization of previously progressive disease was observed in patients with adenocarcinoma of the colon, multiple myeloma, lymphoma, breast carcinoma, and thyroid carcinoma. Responses were minimal and of short duration but most of the patients had received extensive prior therapy.
