BroadPharm--PEG接頭及點擊化學(xué)試劑供應(yīng)商

更新時間:2024-02-23   點擊次數(shù):613次

BroadPharm是一個以客戶為中心的生物技術(shù)公司,總部位于圣地亞哥,BroadPharm致力于為全球客戶提供高質(zhì)量的PEG接頭、Click Chemistry試劑、ADC接頭、 PROTAC接頭、藥物遞送脂質(zhì)、核苷、亞磷酰胺和標(biāo)記試劑。BroadPharm成立于2009年,生產(chǎn)超過2000種分散的,高純度的聚乙二醇(PEG)試劑,目前這些PEG試劑廣泛應(yīng)用于生物偶聯(lián)、抗體-藥物偶聯(lián)(ADC)治療、藥物遞送和診斷領(lǐng)域。

主要產(chǎn)品線:

*PEG接頭

*點擊化學(xué)試劑

*標(biāo)記染料

*ADC接頭


1. PEG接頭(PEG linker

PEG連接劑,也稱為PEG試劑,是一種化學(xué)功能化的聚乙二醇(PEG)連接劑。由于其水溶性、無毒性、低免疫原性和明確的鏈長,PEG連接劑作為交聯(lián)劑在偶聯(lián)和生物標(biāo)記方面特別有吸引力。

PEG化是將PEG連接體連接到藥物、蛋白質(zhì)或囊泡等分子上的過程。由于其高水溶性和非免疫原性,PEG已被廣泛用于制藥和生物技術(shù)研發(fā),以提高藥物的溶解度和穩(wěn)定性,優(yōu)化DMPK并發(fā)現(xiàn)新的遞送形式。BroadPharm的PEG-Linker代表一種高純度的特定單一純分子,這些單分散PEG是用設(shè)計的PEG長度和各種官能團設(shè)計的。

BroadPharm能夠提供的PEG接頭類型:

2.點擊化學(xué)試劑(Click Chemistry):

點擊化學(xué)已廣泛應(yīng)用于制藥和生物技術(shù)研發(fā)。在第一代Click Chemistry,是在末端炔烴和疊氮化物之間的反應(yīng)中需要Cu(I)作為催化劑。Cu(I)離子的毒性會對生物分子造成氧化損傷。第二代Click Chemistry采用應(yīng)變促進疊氮-炔Click Chemistry,無需催化劑,具有生物相容性。與末端炔烴相比,應(yīng)變環(huán)辛烯的活化能顯著降低。第三代Click Chemistry是四嗪和烯烴(反式環(huán)辛烯)之間的連接。這種高速反應(yīng)也是不含銅的,這是體內(nèi)細胞標(biāo)記的理想選擇。

3.標(biāo)記染料:

熒光試劑已被用于標(biāo)記蛋白質(zhì)、抗體、核酸和其他生物物質(zhì),用于生物標(biāo)記、細胞成像、診斷、蛋白質(zhì)印跡和免疫組織化學(xué)。熒光染料可以連接到氨基(N)或羧基(C)末端,或者通過點擊化學(xué)進行連接。

4.ADC接頭:

抗體藥物結(jié)合物(ADC)是一類由抗體通過適當(dāng)?shù)倪B接子/接頭與藥物負載物鏈接在一起的高效生物藥物。連接劑分為可降解和不可降解兩個家族。

① 可降解連接劑的ADC,以Adcetris(由Seattle Genetics推出)代表,其結(jié)構(gòu)如下所示:

② 對于不可降解連接劑的ADC,它依賴于ADC內(nèi)部化后抗體的降解,以Kadcyla代表(由Genentech和Roche推出),其結(jié)構(gòu)如下所示:
