Thermodynamics of the thallium alkanoates VIII. Heat capacity and derived thermophysical properties of thallium(I) propanoate and pentanoate at temperatures from 6 K to 490 K
(Elsevier, 1994-09)
Heat-capacity measurements by adiabatic calorimetry at temperature T = 5 K to 350 K were supplemented by differential-scanning calorimetry (d.s.c.) into the liquid region on thallium(I) propanoate and pentanoate. Apparent ...
Synthesis of a disulfide cross-linked DNA triple helix
(Elsevier, 1994-06-27)
An intramolecular DNA triple helix incorporating a disulfide cross-link has been synthesized. Potassium permanganate footprinting and UV melting analysis demonstrate that the cross-link increases the conformational stability ...
Pharmacophore elements of the TIPP class of delta opioid receptor antagonists
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1994-10)
A series of tri-and tetrapeptides sharing the amino-terminal dipeptide unit Tyr-Tic, found in the high-affinity delta opioid receptor antagonist Tyr-Tic-Phe-Phe (TIPP), was prepared and evaluated in receptor binding assays ...
Specific steroid response from a nonspecific DNA element
(Elsevier, 1994-06)
A fundamental dilemma of steroid hormone regulation is how specific transcription is attained in vivo when several receptors recognize the same DNA sequence in vitro. We have identified an enhancer of the mouse sex-limited ...
