Insulin has a trophic effect on pancreatic acinar tissue, so the pancreas might be expected to atrophy in persons who have diabetes. Accordingly, we analyzed the density, contour (smooth or lobulated), and thickness of the pancreas on CT scans of diabetic patients and compared the results with those in control subjects. The prevalence of pancreatic… (More)
Based on the structure of R115777 (tipifarnib, Zarnestra), a series of farnesyltransferase inhibitors have been synthesized by modification of the 2-quinolinone motif and transposition of the 4-chlorophenyl ring to the imidazole or its replacement by 5-membered rings. This has yielded a novel series of potent farnesyltransferase inhibitors.
The evaluation of structure-activity relationships associated with the modification of the R115777 quinolinone ring moiety displaying potent in vitro inhibiting activity is described.
A series of pyrimidyl-5-hydroxamic acids was prepared for evaluation as inhibitors of histone deacetylase (HDAC). Amino-2-pyrimidinyl can be used as a linker to provide HDAC inhibitors of good enzymatic potency.
Replacement of the 1-methylimidazol-5-yl moiety in the farnesyltransferase inhibitor ZARNESTRA series by a 4-methyl-1,2,4-triazol-3-yl group gave us compounds with similar structure-activity relationship profiles showing that this triazole is potentially a good surrogate to imidazole for farnesyltransferase inhibition.
A case of malignant peritoneal mesothelioma is described. The diagnosis was established by immunohistological studies after CT-guided percutaneous puncture of a small intraabdominal nodule. The clinical and radiological signs were non-specific. Survival period was short because of the absence of curative treatment.
A case of an alobar holoprosencephaly with cyclopia diagnosed by prenatal ultrasound is reported. At 23 weeks of gestation, abortion was performed. The holoprosencephalic aborted foetus was studied as completely as possible. Skull X-rays, cranial computed tomography, and magnetic resonance images are discussed and compared with the necropsy findings.
Pursuing our efforts in designing 5-pyrimidylhydroxamic acid anti-cancer agents, we have identified a new series of potent histone deacetylase (HDAC) inhibitors. These compounds exhibit enzymatic HDAC inhibiting properties with IC(50) values in the nanomolar range and inhibit tumor cell proliferation at similar levels. Good solubility, moderate… (More)
A series of (4-chlorophenyl)-alpha-(1-methyl-1H-imidazol-5-yl)azoloquinolines and -quinazolines was prepared. These compounds displayed potent Farnesyl Protein Transferase inhibitory activity and tetrazolo[1,5-a]quinazolines are promising agents for oral in vivo inhibition.
