  Antiproliferative, antiandrogenic and cytotoxic effects of novel caffeic acid derivatives in LNCaP human androgen-dependent prostate cancer cells

  摘要：

  Caffeic acid and its naturally occurring derivative caffeic acid phenethyl ester (CAPE) have antiproliferative and cytotoxic properties in a variety of cancer cell lines without displaying significant toxicity toward healthy cells, and are considered to be potential anticancer agents. However, little is known about their effects on prostate cancer cells. We synthesized and evaluated the effects of caffeic acid, CAPE (2) and 18 synthetic derivatives on cell viability and androgen-dependent cell proliferation, subcellular localisation and expression of androgen receptor (AR) and secretion of prostate-specific antigen (PSA) in LNCaP human hormone-dependent prostate cancer cells. Several synthetic derivatives of CAPE were strong, concentration-dependent cytotoxic agents in LNCaP cells with IC50 values in the 6.8-26.6 mu M range, potencies that were up to five-fold greater than that of CAPE (33.7 +/- 4.0 mu M). A number of caffeic acid derivatives were inhibitors of androgen-stimulated LNCaP cell proliferation with concomitant inhibition of DHT-stimulated PSA secretion. Compound 24 was the most cytotoxic and antiproliferative caffeic acid derivative (IC50 values of 6.8 +/- 0.3 and 2.4 +/- 0.8 mu M, respectively) inhibiting DHT-stimulated cell proliferation and PSA secretion statistically significantly at concentrations as low as 0.3 mu M. Exposure to DHT increased cytoplasmic and nuclear AR levels and co-treatment with increasing concentrations of compound 24 or CAPE (2), notably, further increased these levels. In conclusion, a number of synthetic derivatives of caffeic acid are potent inhibitors of androgen-dependent prostate cancer cell proliferation and viability, acting, at least in part, via an antiandrogenic mechanism that involves increased nuclear accumulation of (presumably inactive) AR.

  Hypertension is a crucial risk factor for cardiovascular diseases and contributes to one third of global mortality. In addition to conventional antihypertensive drugs such as captopril. naturally occurring phytochemicals and their analogs are used for reducing the risk and occurrence of hypertension. Herein, we demonstrate the possible use of caffeic acid and its derivatives in the treatment of hypertension through multi-target modulation of renin-angiotensin-aldosterone system (RAAS). Caffeic acid along with its nineteen novel derivatives, chlorogenic acid, quercetin and captopril were all investigated for the inhibition of renin and angiotensin converting enzyme (ACE) activities and production of aldosterone. Compound 22 with CH2CH(Ph)(2) moiety exhibited the strongest renin inhibition (IC50=229 mu M) among all compounds tested (P <= 0.05). Caffeic acid was the weakest renin inhibitor (IC50=5704 mu M) among all the compounds assayed. Similar to renin inhibition, compound 22 (IC50=9.1 mu M) also exhibited about 47 times stronger ACE inhibition compared to the parent compound. Analysis of aldosterone revealed that compound 8 with n-Pr moiety was the strongest modulator of aldosterone production among all the derivatives (P <= 0.05). Toxicity analysis using human fibroblasts (WI-38 cells) confirmed the non-toxic manifestations of caffeic acid and its derivatives in comparison to clinically used drug captopril.
