1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

We have developed new, simple, and efficient procedures for the synthesis of two promising histone deacetylase inhibitors (HDIs), CI-994, (N-(2-aminophenyl)-4-acetylaminobenzamide), and MS-275 (N-(2-aminophenyl)4-[N-(pyridine-3-yl-methoxycarbonyl)aminomethyl]benzamide) from commercially available acetamidobenzoic acid and 3-(hydroxymethyl)pyridine, respectively. The procedures provide CI-994 and MS-275 in 80% and 72% overall yields, respectively. We found that the combination of four HDIs (CI-994, MS-275, SAHA, and TSA) with retinoids all-trans-retinoic acid (ATRA) or 13-cis-retinoic acid (13-CRA) or our atypical retinoic acid metabolism blocking agents (RAMBAs) 1 (VN/14-1) or 2 (VN/66-1) produced synergistic anti-neoplastic activity on human LNCaP prostate cancer cells. The combination of 2 and SAHA induced G1 and G2/M cell cycle arrest and a decrease in the S phase in LNCaP cells. 2+SAHA treatment effectively down-regulated cyclin D1 and cdk4, and up-regulated pro-differentiation markers cytokeratins 8/18 and pro-apoptotic Bad and Bax. Following subcutaneous administration, 2, SAHA or 2+SAHA were well tolerated and caused significant suppression/regression of tumor growth compared with control. These results demonstrate that compound 2 and its combination with SAHA are potentially useful agents that warrant further preclinical development for treatment of prostate cancer.
