(R)-69
(''R'')-69 (3IQ) is a tetrahydropyridine derivative which acts as a 5-HT2A receptor agonist, with 4.6x selectivity over 5-HT2B and 49x selectivity over 5-HT2C. It has a 5-HT2A Ki of 680nM and an EC50 of 41nM. (''R'')-69 is a biased agonist selective for activation of the Gq coupled signalling pathway, with much weaker activation of the β-arrestin 2 coupled pathway. In animal studies it produces antidepressant-like activity but without producing the head-twitch response associated with psychedelic effects. See also * AAZ-A-154 * RU-24969 * SN-22 SN-22 is a chemical compound which acts as a moderately selective agonist at the 5-HT2 family of serotonin receptors, with a Ki of 19nM at 5HT2 subtypes vs 514 nM at 5-HT1A receptors.

BMW R69
The R69S, R69US, and R69 are motorcycles, fitted with 594 cc boxer twin engines, that were manufactured by BMW in Munich, Germany. Production history From 1955 to 1969, 15,347 of these 594 cc shaft-drive, opposed twin motorcycles were built. The R69 was produced from 1955 to 1960, the R69S was produced from 1960 to 1969, and the 42 hp R69US was produced from 1968 to 1969. These models were designed as relatively high powered, high compression sport bikes, although the Earles fork R69 and R69S came with sidecar lugs installed on the frames. These lugs were deleted from the telescopic fork "US" models. The low compression R60/2, produced from 1955 to 1960, was designed primarily for sidecar use, though it was popularly used as a solo bike, along with the 30 hp R60US, which was produced between 1968 and 1969. The sport-oriented R69S, R69US, and R69 succeeded the plunger-framed 1951 to 1955 R68, which had an engine very similar to that in the later R ...
