This study was synthesized: 1-(4-(3-methyl-3-phenylcyclobutyl)thiazol-2-yl)-3-phenylthiourea and 1-(4-chlorophenyl)-3-(4-(3-methyl-3-phenylcyclobutyl)thiazol-2-yl)thiourea. Fourier-Transform Infrared (FT-IR) spectroscopy Nuclear Magnetic Resonance (NMR) were used to characterize the molecular formula.

VARIATION in taste sensitivity to the bitter compound phenylthiocarbamide (PTC) is one of the best known Mendelian traits in human populations, ranking alongside eye color and blood types in the canon of classic examples. Much of PTC’s appeal arises from the fact that it is nearly impossible to guess one’s phenotype until explicitly tested, yet, when tested, the phenotype is so striking as to b...

Variations in the human karyotype have been found in association with a variety of congenital anomalies and also in the normal population (Miller and Mukherjee, 1962; Court Brown, 1967). Court Brown's population studies (1967) have revealed that between 2 and 3%o of the normal adult population has a karyotype with structural autosomal variations. Occasionally, homologous autosomes reveal differ...

Cigarette smoking appears to be on the increase in adolescents. The initiation of regular smoking nearly always begins before adulthood. It is therefore crucial to find ways of identifying those children most vulnerable to nicotine addiction and prioritizing them for preventive measures. We hypothesized that individuals who, in a simple taste test, perceive phenylthiocarbamide (PTC) as bitter m...

The cytotoxic activities of three new synthetic catechol analogues, beta-[(p-hydroxyphenyl)amino]alanine (Compound 1), N delta-(p-hydroxyphenyl)ornithine (Compound 2), and N delta-(m-hydroxyphenyl)ornithine (Compound 3), were determined against 10 human melanoma and 5 nonmelanoma cell lines. Activities of L-DOPA and 3,4-dihydroxybenzylamine were also measured. Dose-response curves were obtained...

This is a book, designed for popular consumption, that lists a number of normal characters held to be inherited in man. Many traits are scarcely "treasures," as might be inferred from the title. They pertain chiefly to physical characters, especially those of the face and other readily inspected areas. Much of the material would appear to have been obtained from students in the author's class o...
