Salomon Zender Langer (born 12 October 1936) is an Argentinian pharmacologist whose family had fled from Poland to Argentina in the early 1930s and were thus saved from the Holocaust during the Second World War.

Career

He was born in Buenos Aires, Argentina and graduated in 1960 from the School of Medicine of Buenos Aires University. Starting in 1963 with a Rockefeller Foundation Fellowship he joined the Department of Pharmacology at Harvard University until the end of 1966. His research was on the mechanisms involving denervation supersensitivity.The onset of denervation supersensitivity. Langer SZ, Trendelenburg U. J Pharmacol Exp Ther. 1966 Jan;151(1):73-86 with Ullrich TrendelenburgDemonstration by the histochemical fluorescence method of the prolonged disappearance of catecholamines from the denervated nictitating membrane of the cat.

Langer SZ, Draskóczy PR, Trendelenburg U. J Pharmacol Exp Ther. 1967 Aug;157(2):255-73. with whom he became lifelong friends.

He spent two years (1967-1969) in Cambridge, England with :de:Leslie IversenEffects of phenoxybenzamine on the uptake and metabolism of noradrenaline in the rat heart and vas deferens.

Iversen LL, Jarrott B, Langer SZ. Br J Pharmacol. 1968 Nov;34(3):693P-694P. and at the Institute of Animal Physiology with Marthe Vogt where he worked on norepinephrine(NE) uptake and the regulation of NE release elicited by nerve stimulation as well as the metabolic fate of the released neurotransmitter.Noradrenaline release from isolated muscles of the nictitating membrane of the cat S. Z. Langer, Marthe Vogt J. Physiol. 1971 April; 214(1): 159–171. In 1969, Dr. Langer returned to Argentina where he was appointed Director of the Institute for Pharmacological Research.

The work started in Cambridge continued at the Institute in Buenos Aires during the years 1969-1976, leading to the discovery of the presynaptic inhibitory Alpha-adrenoceptors on noradrenergic nerve terminals and their role in the modulation of the NE release during nerve stimulationPossible physiological significance of the initial step in the catabolism of noradrenaline in the central nervous system of the rat M.

In 1974, Dr. Langer discovered the Alpha-2 adrenoceptorsEvidence for the presynaptic location of the alpha-adrenoceptors which regulate noradrenaline release in the rat submaxillary gland Ester J.

Z. LANGER, Edda Adler-Graschinsky, O. Giorgi. Nature, vol. 265, no. 5595, pp. 648-650, 1977

During the years 1975-1976, he provided the first extensive and rigorous evidence "in vitro"The effects of the 2-amino-tetrahydronaphthalene derivative M7, a selective α 2 -adrenoceptor agonist in vitro N.

In the summer of 1976, Dr. Langer became Head of the Department of Pharmacology at the Wellcome Research Laboratories in Beckenham, Kent, UK and in 1976 he was appointed Director of Biology at :fr:Sanofi-Synthélabo Research in Paris where he later became the Research Director and Vice-President.

The research team directed by Dr. Langer discovered between the years 1979-1980 a specific, high-affinity binding site labeled with for 3H-imipramineASSOCIATION OF HIGH AFFINITY 3H-IMIPRAMINE BINDING SITES WITH THE SEROTONIN TRANSPORTER; POSSIBLE ROLE OF ENDOGENOUS MODULATORS S.

Throughout the 80's Dr. Langer continued his work on presynaptic autoreceptors regulating NE, DA and 5-HT release and reported the interactions in neurotransmission between the neuronal transporter and the corresponding autoreceptor.

During the 23 years at Synthelabo, Dr. Langer discovered and developed five compounds : diltiazem, a calcium antagonist (for coronary insufficiency); betaxolol, a beta-1 adrenoceptor selective antagonist for hypertension and also for local use in the treatment of glaucoma; zolpidem, a selective full agonist of the alpha-1 subunit of the benzodiazepine-GABA-A receptor (for insomnia) and mizolastine, a peripherally acting histamine H-1 receptor antagonist which also inhibits the formation of leukotriens(for allergic diseases).

In 2000, Dr. Langer moved to Israel where he continued research projects in drug discovery for major depression and Alzheimer's disease. In 2014, Dr. Langer founded the drug company Synaptic Pharma Ltd to develop Eliprodil, a noncompetitive antagonist of the ionotropic NMDA receptor for a rapid onset antidepressant action in severely drug-resistant depressed patients.
