IDENTIFICATION: sec-Butylamine is a colorless liquid with an ammoniacal odor. It is miscible with water and most organic solvents. Formulated products include phosphate and carbonate salts. Mixed solutions are not stable beyond three days and concentrates or mixed solutions require protection from direct ight or extremes in temperatures. sec-Butylamine is a fungicide particularly effective for the control of fruit rotting fungi. ANIMAL STUDIES: Groups of dogs were administered this compound as the carbonate or acetate salt and data were recorded for heart rate, respiration, blood pressure and EEG apparatus. IV administration of either the acetate or carbonate resulted in elevated blood pressure, heart rate and respiration. Intragastric administration of larger doses resulted in similar responses. Groups of rats 20 males and 20 females were utilized in a two litter generation, four generation. The Fo parents were allowed to bear six additional litters. The F1b, 2b and3b litters were used as parents for the following generation and maintained for varying periods (162-202 days after weaning their respective litters). Reproduction indices, fertility index, sestation index, viability index and lactation index were normal. A reduction of growth was noted throughout the study at the high dietary level. Reproduction was unimpaired for any of the eight litters produced by the Fo generation. Groups of rabbits were fed sec-butylamine phosphate in the diet and subjected to a two generation, one litter per generation reproduction study. Mortality of several animals was evident at the high dose. Animals switched from the high dose to a lower dose had no effect on fertility, duration of gestation, delivery of live progeny or lactation indices in both generations examined. Growth of the progeny in the F1 generation was normal, while it was slightly depressed in the F2. There was no effect of butylamine acetate noted on survival of offspring in either generation. Groups of Dutch Belted does (19 rabbits per group) were administered sec-butylamine daily from Day 8 through 18 of gestation. Mean fetal weights were lower than controls and a decreased viability of live fetuses was noted at the high dose level. There were no differences from controls with respect for reproduction, sex distribution of fetuses or the number of malformations found. Groups of 10 male and 10 female rats were fed sec-butylamine acetate in the diet for 3 months. At the high dose level a significant growth reduction was noted. A dose related leukopenia in both males and females was recorded. Gross and microscopic examination of tissues and organs showed no adverse effects of dietary sec-butylamine. Six male and six female rabbits were treated dermally for 20 days. A surfactant was present in the aqueous solution. The skin of half the animals was abraded prior to the initiation of the study. There was no mortality and only one animal of the abraded group showed adverse reactions (diarrhea) during the study. Growth, clinical chemistry, hematology and gross and microscopic examination of the tissues and organs were normal. The carcinogenic potential of sec-butylamine was judged to be low based on long term studies. In a feeding study using cows, residues of sec-butylamine were found in muscle, liver, fat and kidney. Data on the presence in urine and feces suggest it is easily absorbed in to the blood and excreted in the urine. Urinary samples from two dogs treated with sec-butylamine were acidified and distilled. A diphenylhydrazone was formed which corresponded to the product formed from a reaction with methyl ethyl ketone.[

Copper-free Sonogashira coupling in amine–water solvent mixtures
摘要:
Extensive study of different amine-water solvent mixtures was carried out for copper free Sonogashira coupling of aryl iodides. The influence of the palladium sources, ligands, amine-water ratio and further additives was also evaluated. Application of sec-butylamine-water mixture proved to be an excellent medium for rapid and efficient coupling of aryl-iodides at ambient temperature in the presence of PdCl2(PPh3)(2) as catalyst.

wherein ring A represents the ring of the formula (a):
in which R1 is a nitro group, an amino group, a substituted amino group or a halogen atom, or the ring of the formula (b):
in which R1′ is the group such as an alkyl group or an alkenyl group; R2 to R5 independently represent the group such as an alkyl group or an alkenyl group; with the proviso that at least one of R2 to R5 is an alkenyl group, or acid addition salts thereof.
The invention provides mitochondria-targeted chemiluminescent agents and their use in methods of photodynamic therapy (PDT). In particular, the invention provides compounds of general formula (I), and their pharmaceutically acceptable salts: (I) in which A represents a chemiluminescent moiety; each L, which may be the same or different, is either a direct bond or a linker; each B, which may be the same or different, represents a mitotropic moiety; n is an integer from 1 to 3, preferably 1; and x is an integer from 1 to 3, preferably 1. Such compounds find particular use in the treatment of deeply- sited tumours, e.g. glioblastoma multiforme (GBM), when used in combination with a photosensitizer or photosensitizer precursor.
The present invention is directed to cyclopropylamine derivatives which are LSD1 inhibitors useful in the treatment of diseases such as cancer.

Herein, we report the palladium‐catalyzeddirectarylation of unactivated aliphatic C−H bonds in free primary amines. This method takes advantage of an exo‐imine‐type directing group (DG) that can be generated and removed in situ. A range of unprotected aliphatic amines are suitable substrates, undergoing site‐selective arylation at the γ‐position. Methyl as well as cyclic and acyclic methylene groups
