3-Dimethylaminopropylamine Other Applications

Application 1.
CN201511019713.3 discloses an artemisinin derivative and a synthesis method and application thereof. The artemisinin derivative is 3-Dimethylaminopropylamine -10-azadeoxyartemisinin, which uses artemisinin as a raw material and is successively mixed with N. , 3-Dimethylaminopropylamine and p-toluenesulfonic acid reaction. By investigating the proliferation inhibitory activity of the derivative on various human tumor cell lines and human normal cell lines, the applicant found that it can inhibit human bladder cancer cells T-24, human ovarian cancer cells SK-OV-3, and human gastric cancer cells MGC80- 3 All three cell lines showed significant proliferation inhibitory activity and had good potential medicinal value, and were expected to be used in the preparation of various anti-tumor drugs.

Application three,
CN201911150842.4 discloses a preparation method of an amphiphilic polymer-modified ultrafiltration membrane, which belongs to the technical field of membrane separation. Alkyl-4,4′-diaminodiphenylmethane and 3-Dimethylaminopropylamine were dissolved together in a mixed solution of dimethylformamide and triethylamine, and copolymerized at low temperature to prepare polymer amide polymer, 2. The polyamide polymer is reacted with 1,3-propane sultone to obtain amphiphilic zwitterionic polyamide, 3. The amphiphilic zwitterionic polyamide is obtained by blending with polysulfone The membrane casting solution is used to prepare the ultrafiltration membrane by the non-solvent induced phase inversion method. In the casting solution of organic solvent, the hydrophobic polyamide segment in the amphiphilic polymer is similar in polarity to polysulfone, which increases its compatibility. In the aqueous phase, the hydrophilic segments in the amphiphilic polymer are enriched on the membrane surface, which plays an antifouling effect.

3-Dimethylaminopropylamine TSCA Test Submission

Subchronic oral administration of 3-Dimethylaminopropylamine (CAS # 109-55-7) by oral gavage in groups of Wistar rats (5/sex/group) at doses of 0, 10, 50 and 250 mg/kg-day Toxicity was assessed for 28 days. Due to the high mortality rate (3/5) in 250 mg/kg females during the initial study, a second trial was conducted in 5 female rats receiving 250 mg/kg and combined data from 10 high-dose females . All animals were necropsied on day 29 of the study. Only women in the high-dose group (4/10) died during the 28-day treatment period. Clinical symptoms were intermittently observed in this group between days 11 and 24 of the study, mainly in concurrent deceased patients, including hypoactivity, unsteady gait, abdominal swelling, and dyspnea. A solitary high-dose male exhibited impaired breathing. Body weight, organ weight, food and water intake, urinalysis, hematology, and clinical chemistry assessments were not significantly different from the control group at any dose. After autopsy, the lungs were discolored with red spots on the surface and foamy contents, and a small isolated spleen, a gross pathological feature found only in deceased females. Microscopic examination revealed marked lesions in these animals, including organ congestion, pulmonary hemorrhage and/or edema, and severe loss and atrophy of splenic lymphoid follicles and lymphatic sheaths. One symptomatic man in the 250 mg/kg dose group exhibited focal epithelial degeneration of the anterior stomach, which the authors claim may be due to the compound’s stimulatory effects.

2. 3-Dimethylaminopropylamine (CAS # 109-55-7) was reviewed for skin sensitization in 15 women Hartley test subject by a maximization test. Induction contained 3 sets of 0.1 mL intradermal shots, flanking the dorsal midline in the shoulder area, with each dual shot consisting of a 1-5% v/v service in pure water (undefined pre-test focus, no topical or systemic action), 1-5% v/v solution in Freund’s total adjuvant (FCA) and FCA alone. After 7 days of induction, difficulty with 0.3 mL of topically applied 1% pure water for 48 h under a closed spot covering the entire examination area. A second 48-hour challenge was executed 21 days later on with topical application of 0.3 mL of 5% solution and also an additional private car, each on either side of the dorsal midline to cover the triplet test site. Although pre-test excitement results were not supplied, the writers concluded that 93% (14/15) of the pets checked had a positive response, compared to 0% (0/6) as well as 100% responses to dinitrogen in the vehicle/FCA control team. The chlorobenzene (positive control) team developed an optimum category of “extreme” sensitization after a 2nd difficulty with 5% N,N-dimethyl-1,3-propanediamine.
